Obrii is a turn-based strategy game developed by Exponenta Games that tasks players with managing a Mars colony. Released October 15, 2025, it’s available on PC, Linux, and Mac. The core loop centers on balancing resources like energy, water, and oxygen while expanding infrastructure to survive the harsh Martian environment. Each mission is handcrafted, guiding players through specific objectives, while the sandbox mode generates unique maps for endless experimentation. The game’s focus is tight but methodical, rewarding careful planning over flashy action. It’s a cerebral challenge for fans of base-building and long-term strategy, with no multiplayer to distract from its solitary, thoughtful design.
In Obrii, each turn lets you assign colonists to tasks, build structures, and manage systems like power grids and oxygen production. You’ll rotate the grid to optimize terrain for solar panels or mining, then adjust worker schedules to match resource demands. Environmental hazards like dust storms force you to adapt, stockpiling supplies or reinforcing structures mid-game. Missions push you toward milestones like launching a rocket, while sandbox mode tests your ability to thrive in randomly generated settings. The interface is clean but dense, with tooltips explaining every mechanic. Progress feels incremental, but a single miscalculation, like overextending oxygen reserves, can collapse your colony in one turn. It’s slow-paced but punishingly precise.
PlayPile data shows 78% of players finish Obrii’s campaign, with an average playtime of 14 hours. Community reviews on Steam rate it 89%, praising its depth but noting a steep learning curve. The sandbox mode sees 30% longer sessions than missions, per telemetry. Common complaints include clunky UI for large colonies and repetitive early-game tasks. Achievement completion sits at 62%, with the “Survival of the Fittest” trophy (lasting 1000 in-game days) earned by 45% of players. Moods are split: 55% label it “thoughtful,” while 30% call it “frustrating.” Critics on Destructure highlight its “masterclass in long-term planning” but warn it’s “not for impatient players.”
Obrii is a niche pick for strategy purists who relish careful base-building and risk management. At $39.99, it’s reasonably priced for its depth, though the lack of hand-holding may alienate newcomers. If you’ve enjoyed games like Oxygen Not Included or Frostpunk, its methodical pacing will feel familiar. The sandbox mode adds replayability, but missions occasionally feel rigid. It’s not a must-play, but its focus on sustainability and logistics makes it a solid choice for late-night strategy sessions.
