Terraforming Mars: Prelude Expansion by Stronghold Games | Engine-Building Card Module with Accelerated Start | Add Corporations and Projects | 1-5 Players Ages 12+ | Requires Base

Jump start your Terraforming Mars sessions with Prelude, a focused expansion that gives each corporation powerful early cards, shaping your engine from the first turn and tightening the race to make Mars habitable.

Draft and play unique Prelude cards that either accelerate terraforming milestones or boost your production engine, giving asymmetric openings and new paths to victory that reward planning and long term strategy.

Add 5 new corporations and 7 project cards tuned to the early game, plus an additional solo challenge to reach 63 TR in time, increasing variety for repeat plays without adding complex rules overhead.

Prelude integrates smoothly with the Terraforming Mars base game and any other expansion or variant, slotting into existing setups so dedicated players can refresh familiar maps and modules with minimal extra setup.

Designed for 1–5 experienced or aspiring strategy gamers ages 12+, this expansion requires the Terraforming Mars base game and is ideal for groups who enjoy engine building, tableau growth, and deep replayability.
