What are Terraforming Mars Prelude Cards and How Do They Work?
At its core, the Prelude expansion is designed to solve one of the most common complaints about the base game: the slow start. Much like how proactive health coverage provides a safety net before you need it, these cards act as a “jumpstart,” effectively skipping the first 1 to 1.5 generations of resource gathering.

These cards are shuffled into their own dedicated deck of 35 cards. During setup, we deal four of these cards to each player. You then choose two to keep and two to discard. The best part? They are completely free to play. Unlike project cards, which cost 3 MC to buy and then a variable cost to play, Prelude cards provide their benefits at zero cost to your starting capital.
The Mechanics: Step 7b
According to the Terraforming Mars: Prelude Game Rules, these cards are played during a special “extra round” known as Step 7b. This occurs right after everyone has selected their corporations and paid for their starting project cards, but before the first generation officially begins.
Mechanically, they function similarly to “green” project cards. You play them, resolve their immediate effects (like gaining production or placing a tile), and then leave them in your play area. Their tags remain visible and active for the rest of the game, which is crucial for triggering synergies or meeting requirements for future cards.
The Power of Wild Tags
Some terraforming mars prelude cards feature a “wild tag” (represented by a question mark). This is a game-changer for flexibility. A wild tag acts as any tag of your choice when you perform an action. For example, if you have a card that requires two Science tags to play, a Prelude card with a wild tag can count as that second Science tag. However, keep in mind that wild tags do not trigger “when played” effects and do not count toward end-game Awards.
| Feature | Base Game Start | Prelude Expansion Start |
|---|---|---|
| Initial Production | Usually 0 (except Corp bonus) | Significant boosts (Heat, MC, Energy) |
| Starting Capital | Standard Corp amount | Corp amount + ~42 MC worth of value |
| Game Pace | Slow build-up | Immediate engine-building |
| Asymmetry | Based only on Corporation | Based on Corp + 2 Prelude cards |
| Average Generations | 12-14 | 10-12 |
Selecting the Best Terraforming Mars Prelude Cards for Your Strategy
Choosing the right cards isn’t just about picking the “strongest” individual card; it’s about crafting a cohesive vision for your Martian empire. Because you see your starting 10 project cards and your two corporation choices at the same time you see your four Prelude options, you can draft a highly specialized start.
Each Prelude card has an average starting value of about 21 MegaCredits. When you pick two, you are essentially walking into the game with an extra 42 MC of infrastructure. If you are looking for a raw data breakdown of every card’s production value, the TM Cards List – terraforming is an invaluable resource for comparing the math behind each choice.
For example, if you draw a hand full of expensive Space cards, you should prioritize Prelude cards that provide Titanium production. If your hand is full of plant-based projects, look for cards that increase your Temperature or provide early Heat production to get those greenery bonuses faster.
Synergies Between Corporations and Terraforming Mars Prelude Cards
The true magic of this expansion happens when your terraforming mars prelude cards perfectly align with your corporation’s unique ability. This creates a “snowball effect” that can make you nearly unstoppable by the mid-game.
- Point Luna: This corporation draws a card whenever you play an Earth tag. If you choose Prelude cards like Allied Bank or Society Support (both of which have Earth tags), you start the game with extra cards in hand and a boost to your economy.
- Robinson Industries: Since Robinson allows you to increase your lowest production for 4 MC, using Prelude cards to “even out” your production (e.g., getting at least 1 in everything) makes their ability much more efficient.
- Valley Trust: This corporation actually lets you draw more Prelude cards! You get to choose an extra one during setup, giving you a three-card “prelude” instead of two. This makes them the kings of the early game.
- Vitor: Since Vitor gives you 3 MC every time you play a card with a non-negative VP icon, pairing them with Prelude cards that have VP icons can give you a massive cash infusion before the first generation even starts.

Top-Rated Prelude Cards for Early Game Dominance
Not all terraforming mars prelude cards are created equal. While the “best” card depends on your hand, certain cards are consistently rated as S-Tier by the community and experts like Terraforming Mars: Prelude | Erik Twice.
1. Acquired Space Agency
This is arguably one of the most flexible cards in the deck. It gives you 6 Titanium and lets you draw two cards. In the early game, Titanium is worth 3 MC each, so you’re getting 18 MC worth of resources plus the card draw. It’s a fantastic way to enable a “Space strategy” from Generation 1.
2. Mohole
If you want to end the game quickly, Mohole is your best friend. It provides a massive +3 Heat production and 3 Heat resources. This allows you to start bumping the temperature track almost immediately, which earns you Terraform Rating (TR) and moves the game toward its conclusion.
3. Supplier
Energy is often the “bottleneck” resource in Terraforming Mars. Many powerful buildings and oxygen-producing plants require energy to run. Supplier gives you +2 Energy production and 4 Steel. This sets you up to play heavy industrial cards without having to waste money on the “Power Plant” standard project.
4. Allied Bank
Simple, clean, and effective. Allied Bank gives you +4 MegaCredit production and 3 MC in cash. It also comes with an Earth tag. Increasing your income by 4 right at the start is equivalent to a permanent TR boost, ensuring you have the funds to buy more cards every round.
5. Great Aquifer
This card allows you to place two ocean tiles immediately. Not only does this give you 2 TR, but it also lets you claim the placement bonuses (usually 2 cards, some titanium, or plants) from the board before anyone else can reach them.
How Prelude Changes Game Pace and Strategic Focus
The introduction of terraforming mars prelude cards fundamentally shifts the “meta” of the game. In the base game, the strategy is often to build a massive “engine” that produces 50+ MC per turn. However, because Prelude speeds up the game, those long-term engines might not have enough time to pay off.
Faster Game Length
A standard game of Terraforming Mars can easily run 3 to 4 hours. With Prelude, the average play time drops to about 90–120 minutes. Most games end 2 to 3 generations earlier than they would otherwise. This means you must be more efficient. If a card takes 5 generations to “break even” on its cost, it might be a bad play in a Prelude game.
Tighter Economic Tension
Paradoxically, even though you start with more resources, money can feel tighter. Because the game moves faster, you have fewer “income phases” throughout the total game. You have to hit the ground running. You can’t afford to spend three generations doing nothing but “passing” to save up money.
This shift in focus is similar to other high-level strategy games where early-game efficiency is king. If you enjoy the tight resource management of titles like Terra Mystica, you’ll find the Prelude expansion brings that same level of intensity to Mars. You can read more about these types of strategic pivots in the-architects-guide-to-terra-mystica-success.
Advanced Tactics: Solo Mode and Expansion Compatibility
For those who prefer to tackle the Red Planet alone, Prelude offers a significant update to the solo experience.
The TR 63 Challenge
In the base game solo mode, your goal is to max out all three global parameters (Temperature, Oxygen, and Oceans) within 14 generations. With terraforming mars prelude cards, the rules change to keep the challenge fair. You now only have 12 generations to finish the job.
Alternatively, the expansion introduces the “TR Solo” variant. In this mode, your goal isn’t to terraform the planet, but to reach a Terraform Rating of 63 within the generation limit. This mode introduces a new Standard Project called Buffer Gas, which costs 16 MC and provides 1 TR, helping you push through those final points when the board is already full.
Compatibility with Other Expansions
Prelude is widely considered the “glue” that holds other expansions together.
- Venus Next: Prelude cards help provide the extra resources needed to fund the Venus track without slowing down the main Mars terraforming.
- Colonies: The extra energy production provided by Prelude cards like Supplier or Power Generation makes it much easier to trade with colonies early on.
- Turmoil: Because Turmoil makes the game harder and more expensive, the “boost” from Prelude is almost essential to keep the pace feeling fun.

Frequently Asked Questions about Prelude Cards
Are Prelude cards suitable for beginners?
The community complexity rating for this expansion is 2.51/5, which is only slightly higher than the base game. While we wouldn’t necessarily recommend it for someone’s very first game (as it adds more starting decisions), it is the first expansion a new player should buy. It makes the game more engaging by removing the “slow start” frustration.
How many Prelude cards do you play with?
In a standard game, each player is dealt 4 cards and chooses exactly 2 to keep. The other 2 are discarded. You play these 2 cards simultaneously with your opponents in player order during the setup phase.
What is the “Wild Tag” on certain Prelude cards?
The wild tag is identified by a question mark icon. It is one of the most powerful tools in the expansion. It allows you to treat that card as having any tag (Space, Plant, Science, etc.) when you are performing an action. This is incredibly useful for claiming Milestones like “Scientist” or “Builder.” Just remember: it doesn’t count for end-game Awards or trigger “when you play a [tag]” effects.
Conclusion
At iBest Health Insurance, we believe that strategic thinking and long-term planning are the keys to success, whether you’re managing your health or colonizing a new planet. Terraforming mars prelude cards are the ultimate tool for players who want to take control of their destiny from the very first turn.
By choosing the right synergies, balancing your production, and adapting to the accelerated pace, you can turn a barren rock into a thriving civilization in record time. This expansion isn’t just an “add-on”—for most fans, it’s the definitive way to play.
