Oxygen Not Included Download for PC Guide

Oxygen Not Included is a brilliant and deeply complex space-colony simulation game released in 2019 by Klei Entertainment. The game drops you into the harsh interior of an alien asteroid, where you must manage a group of cloned survivors called “Duplicants.” Your primary objective is simply to keep them alive as they dig out a home, but survival becomes a brutal race against time as resources deplete and dangerous elements accumulate.

For PC players, the game offers an incredibly deep mechanics loop driven by real-world science and thermodynamics. You aren’t just building rooms; you are managing complex, simulated systems of gas piping, liquid plumbing, power grids, and automation. You must carefully regulate oxygen generation, track rising temperatures that can ruin food crops, and handle toxic waste. Duplicants also have unique psychological needs, requiring you to manage their stress levels through decor, scheduling, and morale-boosting amenities.

Visually, the game utilizes Klei’s signature, charmingly quirky hand-drawn 2D art style, which adds a layer of whimsical humor to the otherwise stressful, high-stakes management gameplay. The highly optimized simulation engine tracks thousands of individual element cells simultaneously. The complete digital package requires just 2 GB of available storage space on your hard drive or solid-state drive (SSD) to deploy.
