FAQ

Yes — the number of cards in your hand is open information, and you should answer promptly when asked, since players need it for things like the Planner milestone. Which cards you hold stays secret.

Source: BGG thread

Yes, the rules don't forbid it — how much is fine is up to your group. The designer says he enjoys keeping negotiation over attack targets in his own games.

Source: BGG thread

Yes — each step of temperature, oxygen or ocean you raise gives you 1 TR, whether it comes from a card, a blue-card action, a standard project or a track bonus. Lava Flows' 2 temperature steps give 2 TR, which is part of why it costs so much.

Source: BGG thread

Yes — raising a maxed parameter is one of the exceptions that doesn't block a card. You skip that part, gain no TR for it, and still get every other effect. The same exceptions apply to standard projects and blue-card actions, so Artificial Lake is playable with all 9 oceans out.

Source: BGG thread

Yes — you raise it the one remaining step and gain 1 TR, and the rest of the card works normally. For Lava Flows you still need a legal volcanic area for the tile.

Source: BGG thread

No — the TR comes from raising oxygen, not from the tile. You can still convert 8 plants or play cards to place greeneries after oxygen is maxed; they give placement bonuses, score 1 VP each and count for adjacent cities.

Source: BGG thread

Yes — follow the icons. A separate TR icon is extra TR on top of the TR from raising the parameter, and you get it even if the parameter is already maxed. Nitrogen-Rich Asteroid gives 3 TR in total (2 + 1 for temperature) when temperature can still rise.

Source: BGG thread

No — that text is just a reminder that a greenery raises oxygen. Only a separate oxygen or TR icon gives an additional increase, so compare a card like Plantation with Nitrogen-Rich Asteroid.

Source: BGG thread

The two early bonus steps on the temperature track each give 1 heat production (production, not heat), reaching 0 °C lets you place an ocean tile, and reaching 8% oxygen raises the temperature 1 step. Each extra raise gives its own TR, and they can chain: an oxygen raise to 8% can push temperature to 0 °C and place an ocean, all without spending another action.

Source: BGG thread

Yes — each step is resolved one at a time, so passing a bonus space still gives you its bonus.

Source: BGG thread

The first ocean is placed normally, with its TR, placement bonuses and triggers (such as Arctic Algae). The second can't be placed, so it is skipped: no tile, no TR, nothing triggers, and the card is still legal to play.

Source: BGG thread

No — the 12 blue areas take only ocean tiles and the 3 named city areas (Noctis City, Phobos Space Haven, Ganymede Colony) take only the city from the card of that name, unless a card explicitly says otherwise. Only Mohole Area, Mangrove and Protected Valley put other tiles on ocean areas. Ocean areas stay reserved even after all 9 oceans are placed.

Source: BGG thread

The areas whose names are printed in bold on the map. On Tharsis these are Tharsis Tholus, Ascraeus Mons, Pavonis Mons and Arsia Mons, the same four listed on Lava Flows. Elysium's are Hecates Tholus, Elysium Mons, Olympus Mons and Arsia Mons; Hellas has none.

Source: BGG thread

No — any tile may be placed on them following the normal rules. They only matter for cards that require a volcanic area, and once they are all covered, Lava Flows and Lava Tube Settlement can no longer be played.

Source: BGG thread

No — only the city placed by the Noctis City card may ever go there. Not Capital, not Tharsis Republic's city, not a greenery or special tile. Capital uses the white tile; Noctis City uses an ordinary city tile.

Source: BGG thread

Yes — they are city tiles, so they count for anything that counts cities or city tiles in play, such as Mayor, Landlord, Immigration Shuttles, Pets and Tharsis Republic's 3 M€ bonus. They are not on Mars, so effects marked ON MARS with an asterisked city icon (Zeppelins, Martian Rails, Tharsis Republic's production effect) ignore them, and no greenery can ever be adjacent to them.

Source: BGG thread

The ocean areas and the three named city areas (Noctis City, Ganymede Colony, Phobos Space Haven). An area already claimed with Land Claim also counts as reserved, for its owner. Volcanic areas are not reserved.

Source: BGG thread

Mostly theme and a sense of game length. In practice it tells you which way to pass in the Draft variant (clockwise in even generations, counter-clockwise in odd) and helps track the first player; it only affects the outcome in solo, which ends after generation 14.

Source: BGG thread

Use substitutes — none of the components are meant to be a limit. If you run short of player markers, use an unused color for your production tracks and used actions and keep your own color for tiles and TR; avoid copper-colored cubes, which look like resources.

Source: BGG thread

No — an area is unavailable only if it is reserved, already has a tile, or doesn't exist. Being unable to pay an area's cost (such as a placement fee on some maps) doesn't free you to place elsewhere; you have to wait until you can pay or until the area is taken.

Source: BGG thread

Yes — a special tile carries your player marker, so it is your tile, and greeneries must be placed next to it if possible. That is the main reason special tiles get a marker; it can also open new areas for your greeneries.

Source: BGG thread

No — tiles never stack, and an area with a tile on it is no longer available. That is why Lava Flows can't use a volcanic area that already has a tile.

Source: BGG thread

No — a tile a card places must be placed, so if no legal area exists the card can't be played (for example Lava Flows with every volcanic area covered). The only exception is an ocean when all 9 are already out. The first-edition rulebook says an unplaceable tile doesn't stop the card; the designer issued errata removing that sentence.

Source: BGG thread

No — a special tile is neither a city (except Capital) nor a greenery; it raises no parameter and gives no VP or TR by itself, only what its card says. You do own it (it gets your marker), so it counts for Landlord and tile-counting effects and anchors your greenery placement.

Source: BGG thread

No — a card overrides only the rule it names. Urbanized Area waives city spacing and Ecological Zone adds an adjacency condition, but neither opens up ocean areas. Only cards that explicitly say to place on an area reserved for ocean (Mohole Area, Mangrove, Protected Valley) can.

Source: BGG thread

On any legal area — not on ocean areas or the reserved city areas. It needs no adjacency to your tiles.

Source: BGG thread

(Official — Publisher confirmed: Carsten Reuter, Schwerkraft-Verlag (German edition)) Yes — Capital is a city in every respect. It gets your marker, can't be placed next to another city, counts for Mayor and Landlord and city effects, and scores 1 VP per adjacent greenery plus 1 VP per adjacent ocean.

Source: BGG thread

Ordinary city tiles, so you can build all of them. The single white city tile is only for the Capital card, to remind you that it also scores adjacent oceans.

Source: BGG thread

Yes — place and resolve them one at a time. You collect the first ocean's placement bonuses before choosing where the second goes, and the second can earn adjacency money from the first.

Source: BGG thread

No — production has no upper limit. When a track goes past 10, leave a marker on 10 and start another one, as many as you need (two markers on 10 plus one on 2 means 22). A cap at the board's maximum is only a house rule.

Source: BGG thread

No — you must be able to perform the decrease in full, so production can't go below 0. M€ production is the only one that can go negative, and never lower than -5; a card that would push it past -5 can't be played.

Source: BGG thread

A minimum — any requirement not marked 'max' is met at that value or higher, so '3 oceans' means at least 3 oceans in play. Requirements marked max (in a red box) mean that value or lower. There are no exact requirements; temperature cards say 'or warmer' only because the numbers are negative.

Source: BGG thread

Yes — requirements are checked only when you play the card from your hand. Once it is in play, its actions and effects keep working for the rest of the game.

Source: BGG thread

Only within three exceptions. You must be able to do every effect except: raising a global parameter that is already maxed, removing another player's resources (optional anyway), and adding resources when you have no card to hold them. Production decreases, removing your own resources and placing tiles are not exceptions. The same rule applies to blue-card actions and standard projects.

Source: BGG thread

Check requirements, pay the full cost, and then the card counts as played; its effects and everything they trigger are resolved in any order you choose, though a triggered effect can't come before what triggered it. Resources a card gives you can't pay its own cost (Media Group's 3 M€ arrives too late), but they can cover a later effect of the same card, like Moss's plant loss.

Source: BGG thread

Yes — you choose the order of a card's immediate effects and of anything they trigger. For example, playing Research with Mars University in play, you can draw Research's cards first and then pick which card to discard to Mars University.

Source: BGG thread

Yes — order the effects so the city goes down first. Immigrant City's own effect gives +1 M€ production for that city, and then the -2 takes you to -5, which is legal. Its own city always triggers it, so the card is a net -1 M€ production.

Source: BGG thread

Yes — losing the plant is an effect, not a requirement. Take the plant from Viral Enhancers' trigger first, then lose it to Moss; Nitrophilic Moss works the same way.

Source: BGG thread

They stack — two discount cards reduce a card by their combined amount. A cost never goes below 0, though, so excess discount is simply lost; Teractor playing a 1 M€ Earth card gets nothing back.

Source: BGG thread

Yes — tag discounts and tag triggers work per tag, so Valley Trust takes 4 M€ off Research, and Research's two science tags trigger Mars University twice.

Source: BGG thread

No — buying a card means paying 3 M€ to put it in your hand (or discarding it). You play it later by paying its printed cost.

Source: BGG thread

Shuffle the discard pile into a new deck as soon as a card needs to be drawn, even in the middle of an action. When dealing the last cards, deal one at a time in player order, reshuffle and continue; if both piles are empty, just stop drawing — the designer has never seen it happen.

Source: BGG thread

The icons, unless there is an asterisk. The text only explains the icons and may be shortened; an asterisk marks an effect the icons can't express, and then the text rules. The designer recommends reading both, since a reading that contradicts either is probably wrong. Translations can be wrong too, but icons are the same in every language.

Source: BGG thread

You discard first, then draw. The designer said in September 2025 that a player could technically draw first because the card lacked an asterisk, but shortly after the official FAQ added the asterisk, so discarding first is the rule.

Source: BGG thread

No — its older wording lacks 'up to', but like every red-bordered removal of another player's resources it means up to 2, so you may remove fewer or none.

Source: BGG thread

It triggers once you have paid for the event, so it can't help pay that event's cost. After that it joins the event's own effects and can be resolved before them; the older 'after you play' wording means the same as 'when'.

Source: BGG thread

Triggers are meant to happen, and any player may invoke anyone's trigger, but forgetting one isn't a rules violation. The designer would let a forgotten bonus be applied later, since anyone could have pointed it out, while takebacks of actual choices are a different matter. Optional effects such as Mars University say 'may'.

Source: BGG thread

Yes — everything a player has played, face-down events and covered cards included, is open information, and you may ask what has been played and how many events someone has. Cards are stacked only to reduce analysis paralysis, so don't keep leafing through opponents' piles. Cards in hand and discards stay hidden.

Source: BGG thread

Yes, as long as that option is playable. An option that achieves nothing only because of the allowed exceptions — a maxed parameter, resources you can't place, resources removed from nobody — is a legal choice.

Source: BGG thread

No — stealing is a package deal: you remove the stated amount from one player and gain exactly what you removed, and the optional-removal exception doesn't apply. Hired Raiders is the exception, since its 'up to' lets you choose a smaller amount. Protection against removal, such as Protected Habitats, also blocks stealing.

Source: BGG thread

Yes — whatever is left of the arrow must be paid first, and then the effect is performed like a played card: fully, apart from the three standard exceptions. You can't do only part of an action, and an 'X' cost must be at least 1, so Power Infrastructure can't spend 0 energy to stall.

Source: BGG thread

No — an event's tags count only while it is being played: they let you pay with steel or titanium, qualify for discounts and trigger 'when you play a tag' effects like Mars University or Olympus Conference. Then the event goes face down and its tags never count again — not for tag requirements or end-game scoring such as the Scientist award.

Source: BGG thread

Some events score VP, some cards count them (such as Media Archives), and every project is meant to happen only once, so they must not be reshuffled into the deck.

Source: BGG thread

Yes — every card triggers off its own tags, so they count for its own effects and trigger its own blue effect. Decomposers gets a microbe from its own microbe tag, and Interplanetary Trade counts its own space tag.

Source: BGG thread

Only your own tags in play — your corporation, Preludes and face-up green and blue cards. Cards in hand, face-down events and other players' cards don't count unless the icon has a red border.

Source: BGG thread

Yes — a corporation's tags count exactly like tags on your played cards, for requirements, Builder or Scientist, and cards that count tags. Prelude tags count too.

Source: BGG thread

Yes — tag-triggered effects fire once for each matching tag. Advanced Ecosystems (plant, microbe, animal) gives Decomposers 3 microbes, Research's two science tags trigger Mars University and Olympus Conference twice, and every card with its own trigger resolves separately in the order you choose.

Source: BGG thread

No — tags have no rules of their own. Only steel (for building tags) and titanium (for space tags) help pay for cards, and tags you already own give no discount unless a card such as Earth Office says so.

Source: BGG thread

Yes — a 'per tag' formula may come to zero; you can still play the card for its tags or VP. Insects counts only plant tags in play, not cards in hand.

Source: BGG thread

Only cards that use that resource, in an action or for VP, and each such card holds just one type. A microbe or animal tag alone isn't enough, so Viral Enhancers or Symbiotic Fungus can't collect microbes. Plants are a standard resource and always go on your player board.

Source: BGG thread

No — an icon without a red border affects only you, so 'any card' or 'another card' means one of your own cards that collects that resource. You can never give resources to another player, even if you want to.

Source: BGG thread

Yes — adding resources you can't collect is one of the three exceptions, so you play the card and simply lose that part. This covers, for example, Eos Chasma National Park with no animal card, and CEO's Favorite Project with no resource on any of your cards.

Source: BGG thread

Yes — you must perform all effects, so adding microbes from Imported Nitrogen isn't optional when you have a valid card. The same goes for blue effects like Decomposers or Ecological Zone.

Source: BGG thread

No — all resources of one type from a single effect go on one card. Imported Nitrogen puts its microbes on one microbe card and its animals on one animal card, and Virus removes its animals from a single card. Separate effects, such as a colony bonus and trade income, may target different cards.

Source: BGG thread

Yes — corporations are cards, so a corporation that collects a resource can receive it from other effects. A card that says 'any card' can also add to itself if it holds that resource, as Comet Aiming and Directed Impactors do.

Source: BGG thread

Opponents removing your plants and the animals and microbes on your cards — which also stops their Predators and plant-stealing cards. It does not protect production, so Birds or Herbivores can still lower your plant production, and you may still remove your own resources. Asteroid Deflection System likewise protects plant resources only.

Source: BGG thread

You must remove one — the removal sits left of the arrow, so it is a cost that has to be paid in full even though its icon is red-bordered; the optional-removal rule covers effects, not costs. It may come from any card, your own included, and Predators can even eat from Predators. With nothing to remove, you can't take the action.

Source: BGG thread

They let you treat a card's global requirements (temperature, oxygen, oceans) as up to 2 steps looser in whichever direction helps: a minimum can be met 2 steps early and a maximum exceeded by 2. For temperature that is 4 °C. They never move a track or give TR, and they don't affect tag requirements.

Source: BGG thread

Yes — requirement modifiers are cumulative, so all three together loosen a global requirement by 6 steps; Kelp Farming becomes playable with no oceans.

Source: BGG thread

No — its action spends 8 heat to raise your TR directly, without moving the temperature. That is useful after temperature is maxed, or to gain TR without bringing the game end closer.

Source: BGG thread

Add 1 resource of the matching kind to one of your cards that already holds at least one resource — animals, microbes, science, floaters and so on. If you have no such card, you can still play it and lose that part.

Source: BGG thread

On the next card you play in the same generation, whether as your second action that turn or on a later turn. It is a discount, not a kickback, and it is lost if you play no other card that generation.

Source: BGG thread

You must own a greenery tile to play it (the requirement has no red border), but its tile can go next to any greenery, an opponent's included. It starts with 2 animals, one for each of its own plant and animal tags, and from then on gains one per plant or animal tag you play.

Source: BGG thread

(Official — Publisher confirmed: Carsten Reuter, Schwerkraft-Verlag (German edition)) It lowers it: you give up 1 energy production to raise your TR 1 step. Anything left of the arrow is a cost; the text is correct and the icon simply lacks its minus sign.

Source: BGG thread

Each science tag you play (including its own when played) triggers it once: either add a science resource, or remove one to draw a card. A card with two science tags triggers it twice, so you can add one and spend it, add two, or spend two. You may let resources pile up.

Source: BGG thread

Only the brown production box in the bottom section of one of your own cards with a building tag, decreases included, applied again as if just played. It copies no tiles, resources, TR or oxygen, and never a production box inside a blue card's action or effect (Underground Detonations). The target is chosen when you play it and can't change.

Source: BGG thread

No — its effect can't be carried out without a valid target, so you can't play it just for its tag. Events never qualify, since none has a building tag.

Source: BGG thread

No — the whole copied box must be performed, decreases included, and lowering production isn't one of the three exceptions.

Source: BGG thread

The same metal that card's tile earned: its production box refers to the placement bonus under the tile it placed, so a titanium area gives titanium production again. You place no new tile; if both mining tiles are out, use the one placed by the card you are copying.

Source: BGG thread

It is discarded whether or not it has a microbe tag — the errata makes the action read 'reveal and discard'. It never goes back on the deck or into your hand.

Source: BGG thread

No — discarding a card is part of its required effect, so you need another card in hand. Mars University is different because its discard is an optional trigger.

Source: BGG thread

The space tags of all your opponents combined, on cards in play when you play it — not events and never your own tags, so it gives nothing in solo.

Source: BGG thread

For each plant, microbe or animal tag you play — its own included — gain 1 plant or add 1 resource to the card you just played, if that card can hold one. Decomposers played with it in play can get 2 microbes, or 1 microbe and a plant. It never stores resources itself, and using card actions doesn't trigger it.

Source: BGG thread

No — it is an effect, not an action. It changes the plant conversion on your player board to cost 7 plants, so it applies every time you convert, as often as you can pay, including the final greenery placement after the last production phase.

Source: BGG thread

Technically yes — passing isn't an action, so the forced first action would simply become your first action in generation 2. It is almost never a good idea. It happens only once per game, not every generation.

Source: BGG thread

(Official — Publisher confirmed: Carsten Reuter, Schwerkraft-Verlag (German edition)) It's free — it isn't the City standard project — and it does trigger Tharsis Republic: +1 M€ production for a city on Mars and the 3 M€ for placing your own city, plus the area's placement bonus. You don't get the standard project's +1 M€ production for it.

Source: BGG thread

The +1 M€ production triggers whenever any player places a city on Mars; the 3 M€ triggers on any city you place yourself, on or off Mars. Building with the City standard project stacks with it: +1 from the project and +1 from Tharsis, plus the 3 M€.

Source: BGG thread

Whenever you pay for something yourself, you may spend heat cubes as if they were M€, as often as you like — including M€ costs on your own Preludes such as Business Empire. It doesn't convert heat into money, so opponents' Hired Raiders can only take real M€, and global events can't take heat.

Source: BGG thread

Yes to both — its own Jovian tag counts when it enters play, so it effectively starts with +1 M€ production, and it gains 1 more whenever any player plays a Jovian tag.

Source: BGG thread

That your TR has already gone up this generation — TR, not VP. Then you may pay 3 M€ for 1 more TR, once per generation like any action.

Source: BGG thread

Whenever you place any tile (city, greenery, ocean or special) on an area with a steel or titanium placement bonus, gain 1 steel production — only 1, even on an area with two cubes. Resources from cards or Preludes don't trigger it. Its two building tags count twice for Builder or Medical Lab but don't change steel's value.

Source: BGG thread

Playing cards with a power tag and the Power Plant standard project. It doesn't discount blue-card actions such as Space Mirrors, and a discount larger than the cost just brings it to 0.

Source: BGG thread

Yes — you are dealt your 2 corporations and 10 project cards (plus Prelude cards, if used) together, look at all of them, and then decide on your corporation and which cards to keep in one go. The only exception is a Beginner Corporation, which you must commit to before any cards are dealt.

Source: BGG thread

No — everyone makes their corporation, Prelude and starting-card choices privately and at the same time. Only afterwards are corporations revealed, in player order, and kept cards paid for.

Source: BGG thread

After everyone has chosen, players go in player order: reveal the corporation, take its starting resources and production, then pay 3 M€ for each kept project card. Prelude cards are played only after all corporations are revealed, again in player order, and then the first action phase begins.

Source: BGG thread

It is meant only for players new to the game. The designer describes it as a teaching aid to drop after about the first game, not for tournaments, and leaves it to the group to refuse it to an experienced player; the rulebook simply offers it to new players.

Source: BGG thread

No — the Beginner Corporation replaces the normal deal of 2 corporations and 10 cards, so a player must ask for it before anything is dealt. The designer called the digital version's option to switch to it after seeing your hand an unfair advantage.

Source: BGG thread

No — a Beginner Corporation keeps all 10 project cards for free; that is part of its value. From the second generation on, research works normally and costs 3 M€ per card bought.

Source: BGG thread

Yes — a new player can take a Beginner Corporation while everyone else chooses from their 2 dealt corporations, and the two kinds are meant to be balanced against each other. With Prelude, the Beginner Corporation player still picks 2 of 4 Prelude cards like everyone else.

Source: BGG thread

(Official — Publisher confirmed: Carsten Reuter, Schwerkraft-Verlag (German edition)) It depends on whether you play with Corporate Era cards, not on which corporation you take. In the standard game (no Corporate Era cards) every track starts at 1 and the corporation's production is added on top, so Thorgate starts at 2 energy production. With Corporate Era every track starts at 0 and only the corporation's production applies, Beginner Corporation included.

Source: BGG thread

Only what your corporation gives — the solo game is always played with Corporate Era, so the standard game's extra 1 production per track is not used, even with a Beginner Corporation.

Source: BGG thread

Yes — setup always counts as part of generation 1, with or without Prelude, so anything that happens during setup happens 'this generation'. The rulebook describes it separately only to explain why generation 1 begins with the action phase.

Source: BGG thread

Neither replaces the normal opening — you still get 10 cards and buy what you want at 3 M€ each. The printed first action is taken as your first action on your first turn, so it is one of that turn's 1–2 actions, and it costs no M€.

Source: BGG thread

Yes — pick the first player any way you like. Giving it to the most recent winner is only a suggestion, and the designer notes there is almost no first-player advantage.

Source: BGG thread

Yes, but only corporations already in play react. Corporations are revealed in strict player order, so Saturn Systems or Splice only trigger on corporations revealed after them. Prelude cards are played after every corporation is out, so they can trigger any corporation.

Source: BGG thread

No — you take 1 or 2 actions per turn, and turns keep going around the table until everyone has passed, so a generation has no action limit. You are out only once you pass, by taking no action on your turn. The two actions in a turn can be the same or different.

Source: BGG thread

No — passing only stops you from taking actions. Other players can still remove your resources or lower your production, and your own effects, like Arctic Algae, keep triggering.

Source: BGG thread

The active player, even for other players' triggered effects. Outside the action phase (for example during production or the final greenery round), the first player decides.

Source: BGG thread

Once per generation per card — mark it with a player marker until the production phase. If a card lists two actions you pick one of them. Corporation and Prelude actions, like UNMI's, follow the same rule, and having several action cards means you can use each of them once.

Source: BGG thread

Only ones where the part that does nothing falls under the three exceptions: spending 8 heat with temperature maxed, Symbiotic Fungus with no microbe card, or an ocean placement when all oceans are out. You can also sell a single card. You can't stall with UNMI without having raised TR, or with an X of 0.

Source: BGG thread

No — having raised your TR this generation is a condition of the action, and you must also pay 3 M€ and gain the TR, so it can't be used as an empty stalling action. TR gained earlier in the generation counts, including setup and Preludes in generation 1.

Source: BGG thread

No — X is always at least 1, and 'pay' and 'spend' mean the same thing. Power Infrastructure must spend energy, Insulation must lower heat production by at least 1, and Sell Patents must discard at least one card.

Source: BGG thread

Yes — looking at the card and discarding it costs nothing, so the action is legal; you just can't buy the card.

Source: BGG thread

No — mandatory triggered effects are part of the action, so they must all be possible (for example, you can only place a tile on an area with a cost if you can pay it). Optional triggers, such as Mars University's 'may', can simply be skipped.

Source: BGG thread

Yes — every action works the same way: meet the requirements and pay the cost, then resolve its effects and everything they trigger in the order you choose, causes before effects. That includes standard projects, conversions, milestones and blue-card actions.

Source: BGG thread

No — the project places a city, and placing a tile isn't one of the exceptions, so with no legal area you can't take it or its production.

Source: BGG thread

Yes — you may still take a project like Asteroid when temperature is maxed, and the rebate triggers because you used a standard project, whatever it achieved.

Source: BGG thread

Yes — each is one action, and one player could take all three milestones and fund all three awards.

Source: BGG thread

Ties are friendly: everyone tied for first gets 5 VP and then no second place is given; if one player wins and several tie for second, each of them gets 2 VP.

Source: BGG thread

No — Banker compares only the M€ production marker on your player board; TR and M€ held don't count, even though TR adds to income.

Source: BGG thread

They count resources you hold at the end, not production. Miner adds steel and titanium together, so you can win it with just one of them; Banker is the award that looks at production.

Source: BGG thread

Every tile you own: cities (including off-Mars cities), greeneries and special tiles. Oceans are owned by nobody, and Land Claim markers aren't tiles.

Source: BGG thread

Yes — only the original solo mode leaves them out. With two players each one is a big swing, since it gains you 5 VP and denies them to your opponent.

Source: BGG thread

No — the current generation is played out until everyone passes, then a normal production phase, then the final greenery conversion, then scoring. There is no generation limit in multiplayer, and running out of cards doesn't end the game either; the players decide how fast to finish terraforming.

Source: BGG thread

In player order, with the same first player as the last generation, each player converts as many sets of plants into greeneries as they want before the next player goes. Tiles are paid and placed one at a time, so plants from a greenery's placement bonus can fund another. It isn't split into 1–2 action turns.

Source: BGG thread

Yes — final greeneries are placed like any other: placement rules apply, you collect placement bonuses and ocean money, and effects like Herbivores trigger. No other actions are allowed then — no standard projects, cards or blue-card actions.

Source: BGG thread

Most M€ left over wins — counting only actual M€, after the final production and greenery bonuses. If that is tied too, the players share the victory; there is no further tiebreaker.

Source: BGG thread

No — Helion can spend heat as if it were M€, but nothing is paid in a tiebreak, so the heat is still just heat and doesn't count.

Source: BGG thread

The separate count is just a convenience for cards worth 1 VP per Jovian tag. Each such card counts all your Jovian tags in play, including its own, so tags are never used up: two such cards with three Jovian tags give 6 VP.

Source: BGG thread

The designer considers Corporate Era without drafting the main game. The standard game, with its extra production and no Corporate Era cards, is a shorter introductory version, and drafting is an optional variant — the rulebook leaves it out for beginners.

Source: BGG thread

Everyone starts with 0 production instead of 1, and the added cards build economies and score VP rather than raise global parameters, so terraforming takes more generations.

Source: BGG thread

Yes — neither is tied to a game mode. New players may take a Beginner Corporation in either the standard or the Corporate Era game, and the draft works with both; solo uses neither.

Source: BGG thread

No — the official draft covers only the 4 cards of each research phase from generation 2 on. The designers left the opening hand undrafted on purpose, so you can hunt for combos in a full hand; drafting it is a house or tournament rule.

Source: BGG thread

Pass clockwise in even generations and counter-clockwise in odd ones. The designers advise against always passing one way, because alternating stops one player from always blocking the same neighbour.

Solo always uses Corporate Era: add all its cards and corporations and start with 0 production plus your corporation's. Your TR starts at 14, there is no draft, milestones and awards aren't used, and 2 neutral cities with greeneries are placed at random. A Beginner Corporation is allowed but not recommended; every corporation ability and starting bonus works as usual.

You must complete terraforming by the end of generation 14 (12 with Prelude); the game always runs the full length, so finishing early just gives you more time to score. Only games you win are scored, after the last plant-to-greenery conversion.

No — terraforming must be finished before that last conversion. The final greeneries are placed without raising oxygen, so if oxygen isn't maxed by then, you lose.

You target the neutral opponent, which is treated as having unlimited resources and production of every kind. Reductions simply happen, steals give you the full amount from the supply, and red-bordered production decreases are always playable. Predators and Ants can take from it too.

They don't raise oxygen (it starts at 0%) and they aren't yours, so they don't anchor your greeneries — with no tiles of your own, your first greenery can go anywhere. They do count as cities and greeneries for other effects: Tharsis Republic gets production for the neutral cities, and Industrial Center or Energy Saving can use them.

(Official — Publisher confirmed: Carsten Reuter, Schwerkraft-Verlag (German edition)) Once, at setup only. Reveal and discard 4 cards: the first cost counts areas like reading from the top left for city 1, the second counts backwards from the bottom right for city 2, and the other two place each greenery by stepping clockwise around its city from the top left. Count only legal areas, skipping reserved areas such as ocean areas.

It hardly matters — the neutral tiles only add variety. The designers simply draw another card; treating 0 as the first legal area or wrapping around is also fine. If a neutral greenery has no legal area, it isn't placed.

No — you take 1–2 actions per turn, but the turn comes straight back to you, so you keep acting until you pass. Each blue-card action is still once per generation.

It means the effect can target any player, yourself included. It doesn't make the effect optional and doesn't require an opponent as the target: red-bordered resource removal is optional, while a red-bordered production decrease must still be done.

No — only red-bordered icons reach other players. 'Any card' just means any of your own cards, not necessarily this one. If you have no eligible card, skip that part and play the card anyway. Teslaract's energy production decrease, with no red border, is your own.

Only when the trigger icon has a red border. Rover Construction, for example, pays you 2 M€ whenever any player places a city, because its city icon is red-bordered. The benefit always goes to the card's owner.

It's optional — you may remove up to the amount shown, or fewer, or none, so Asteroid doesn't force you to remove your own plants. Whatever you remove must come from a single player; you can't split it.

Source: BGG thread

It's mandatory and must be done in full to one player, who may be you. If no opponent has enough of that production you must lower your own; if nobody, you included, has enough, you can't play the card. Splitting the decrease between players isn't allowed.

No — removed resources go back to the supply. You only receive them when the card says 'steal', as Hired Raiders does.

Yes — a red-bordered tile icon covers all players' tiles, so these cards count every city in play, opponents' included. A red-framed requirement works the same way: Rad-Suits needs any two cities in play.
