OBRII

Turn-based strategy game about building a colony on Mars

Take 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.

BUILD MARS COLONY

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?
