Our verdict on Oxygen Not Included
Oxygen Not Included is a single-player space-colony simulation from Klei Entertainment, set inside an asteroid where a crew must survive. It suits players who enjoy balancing connected systems rather than focusing on one management task: oxygen, temperature, excavation, resource allocation, plumbing, power, and colonist needs all shape the colony. Procedurally generated worlds provide places to explore, while the game remains centered on keeping the crew alive and its underground home functioning.
The central appeal is the depth of its colony systems. Players manage oxygen generation and gas circulation, control heat and temperature, build plumbing and liquid delivery, and maintain power sources and grids while responding to overloads. Those tasks sit alongside resource gathering and colonists’ stress and needs, making the simulation broad rather than narrowly focused on one production loop. That breadth will suit players who want multiple systems to plan around; it may be a poor fit for someone seeking a lighter or less demanding simulation.
Oxygen Not Included is a paid desktop game for Windows, macOS, and Linux, with Steam and Epic Games listed as platforms. The Spaced Out! DLC expands the experience with colonies across multiple planetoids, so it is relevant for players looking for more scope beyond the base colony. The game is single-player, and the listed support channel is documentation. Choose it for intricate colony management and procedural exploration; look elsewhere if multiplayer or a simpler, more relaxed management experience is central to your choice.
