Terraforming Mars: Prelude 2 – More Starting Power for TM Veterans
New Prelude cards with ongoing effects, cross-expansion synergies, and 5 fresh corporations — the expansion that rewards players who own the full TM library.
📋 Game Details
Terraforming Mars: Prelude 2 is the sixth expansion for Terraforming Mars and the direct follow-up to one of the most beloved expansions in the game's history. While Prelude 1 was designed to be accessible to everyone, Prelude 2 takes a different approach — it is an expansion built for players who have invested deeply in the full Terraforming Mars ecosystem.
Most of Prelude 2's cards are specifically designed to interact with Venus Next, Colonies, and Turmoil. They introduce Prelude cards with ongoing effects that persist throughout the game — a significant departure from Prelude 1's one-time boosts — and cross-expansion synergies that reward players who have built a comprehensive TM collection.
Players who own the full Terraforming Mars expansion library consistently describe Prelude 2 as the expansion that tied everything together — the cross-expansion synergies create combinations that feel genuinely new even after hundreds of hours of play.
What's New in Prelude 2?
Ongoing Prelude Cards
Unlike Prelude 1's one-time effects, some Prelude 2 cards have persistent effects that continue throughout the game.
Cross-Expansion Synergies
Cards specifically designed to interact with Venus Next, Colonies, and Turmoil — rewarding a complete collection.
5 New Corporations
Fresh corporations designed around the expansion's cross-expansion theme with unique starting abilities.
Standalone Cards
13 Prelude cards and all 5 corporations are playable without any other expansions — accessible entry point.
How Does It Differ from Prelude 1?
Prelude 1 is universally recommended because it works for everyone — every card can be played regardless of which expansions you own. Prelude 2 makes a deliberate design choice to go deeper rather than broader.
The majority of Prelude 2's cards are locked behind other expansions. If you don't own Venus Next, Colonies, or Turmoil, a significant portion of the cards will sit unused in your deck. This is not a flaw — it's the expansion's entire purpose. It rewards players who have committed to the full TM library with cards that create combinations nobody has seen before.
The new ongoing Prelude cards are the most interesting design addition. Rather than a one-time boost that fires at game start and disappears, these cards sit in front of you throughout the game — providing recurring benefits, enabling specific strategies, or unlocking new action options every generation.
