About Mars Incremental
Terraform Mars at your own pace. Here's how.
Build unique machines like the Data Discovery Dome, the Atmospheric Alchemy Array, and the Colossal Core Conduit.
Deploy drones to gather resources, then reinvest in more drones. A sustainable growth strategy, technically.
Raise the heat, the pressure, and the humidity. Cross the threshold and Mars becomes something new.
Unlock talents and unique technologies across an ever-growing tree of possibilities.
- A short, active incremental game
- Terraforming that visibly reshapes the planet
- New upgrades keep surfacing from places you weren't watching
- Permanent unlocks that carry across every run
Formerly known as Mars I.D.L.E.
