Procedurally generated maps and two distinct modes—sandbox and survival—deliver endless replayability as you balance resource management, terrain manipulation, and the ever-growing needs of your settlers.

Turn-based strategy game about building a colony on MarsTake command of humanity’s expansion to Mars in this turn-based colony builder. Use each turn to deploy terraforming tools — reshape terrain, create mineral deposits, or enhance existing resources to support your growing colony. Build homes for settlers, construct vital infrastructure, and work toward a self-sustaining future on the Red Planet.

Develop a sustainable habitat for your settlers by installing water pumps, cultivating fertile land, harnessing solar energy, and extracting valuable minerals.Plan your layout carefully — building placement matters. Each structure grants adjacency bonuses that can make or break your strategy.

TERRAFORMING

Each turn gives you the chance to alter the terrain with a terraforming kit.Need water? Place a water drop tile in a canyon and watch the flatlands bloom.
Missing resources? Enrich the area by creating new mineral deposits or extending those already present.

 SANDBOX & SURVIVAL MODES

Face ever-changing worlds in sandbox mode, where each map and terraforming kit is procedurally generated for endless replayability.Or challenge yourself in survival mode, where each step brings more settlers and rising demands.Endless growth… or inevitable collapse — how far can you go?

✦ AI summary

Players praise this affordable puzzle-strategy game as a solid resource management challenge where you must balance competing demands like power, water, and colonist housing while navigating terrain constraints across turn-based missions. While the engaging core mechanics and accessibility appeal to city-building fans, some feel the game is incomplete with limited mission variety and objectives, leaving questions about whether future updates will expand the content and resource types available.

Recommended Oct 18, 2025
I've played through the first 8 or so missions of the campaign, so I haven't gotten the full experience or into the sandbox yet. So far this strikes me as a kind of puzzler base builder in which you have a certain number of turns in order to achieve the objective. To do so, you have to juggle resources like power and workers. Its pretty easy on the eyes for what it is too and the audio is well suited to it. I saw that this game has been out for two days with no reviews and it made me sad. Definitely worth the meager price. Try it out at least.

Completed the whole game in 24 hours, not bad for the price tag. Recommend to anyone liking city building type games. Reasonably challenging getting to balance competing requirements. For example a farm needs water, power and 5 colonists to run. So housing, water extractor and solar panels need to be built. Of course this consumes resources so a factory is also required to manufacture resources. Getting the balance right between resource production levels, and accessing the resource source in a hostile terrain which needs terraforming is the core of this game. Master that and you will succeed in completing the missions on offer. My impression is a solid game but incomplete, perhaps it will get expanded resource types, and mission objectives which currently are very limited in scope? At the moment is simply build x amount of something by y number of turns, so there is plenty of room to mod and improve the game from it's current state, for example adding extra resource types and mission objectives.
