Obrii

Obrii is a turn-based strategy game about building a colony on Mars. Each turn, you use terraforming tools to reshape terrain, create mineral deposits or improve existing resources, while building homes and infrastructure for settlers. Your goal is to make the colony self-sustaining.

Build the colony

You develop a habitat by installing water pumps, cultivating fertile land, harnessing solar energy and extracting minerals. Structure placement matters: buildings grant adjacency bonuses that can shape your strategy.

Terraform Mars

Each turn gives you a chance to alter the terrain with a terraforming kit. Place a water drop tile in a canyon to help flatlands bloom, or create mineral deposits and extend existing ones to increase local resources.

Game modes

In sandbox mode, maps and terraforming kits are procedurally generated, creating ever-changing worlds. Survival mode brings more settlers over time, along with rising demands.
