Mars Colony

3D building and simulation: you land with four colonists and a module, and it's up to you to give Mars its first city. Free, in your browser.

Four colonists, one module and a whole red planet. Never let them run short of air, water or food, and grow the colony until Mars can breathe.

Preparing for landing…

Pick a building below and tap the ground to place it. Green means you can; red means you can't.
Every colonist breathes, drinks and eats each sol. At the top you can see what comes in and what goes out for each resource.
Solar panels give nothing at night and very little during a storm: store power in batteries.
Build the landing pad and ships will bring more colonists; they need homes and good morale.
Research in the lab to unlock the factory, fusion, the domes and the towers that will make Mars breathable.
