How to Install

Important: Back up your save_files folder first. If Steam Cloud is enabled in-game, ONI reads from the cloud_save_files folder instead — disable cloud saving or copy the save there.

Download and extract the .zip file to your desktop.

In Steam, right-click Oxygen Not Included → Properties → General and turn off Steam Cloud.

Press Win + R, type %USERPROFILE%\Documents\Klei\OxygenNotIncluded\save_files\ and press Enter.

Backup any existing colony folders in save_files.

Copy the downloaded colony folder (with its .sav file) into save_files.

Launch Oxygen Not Included, choose Load Game and pick the colony.

This save is for the base game. The Spaced Out! DLC uses a different map and rocketry system, so make sure the DLC is disabled from the main menu before loading it.

Frequently Asked Questions

Is this Oxygen Not Included save file safe to use?

Yes. Oxygen Not Included is single-player with no anti-cheat, so loading a save file carries no risk for your Steam account.

Where is the Oxygen Not Included save file located on PC?

Saves are stored in: %USERPROFILE%\Documents\Klei\OxygenNotIncluded\save_files\ — or in cloud_save_files next to it when Steam Cloud is enabled.

Does this save work with Spaced Out!?

No. It was made in the base game. Disable the Spaced Out! DLC from the main menu before loading it.

Are colony achievements unlocked?

Yes. The colony achievements, including opening the Temporal Tear, were completed in this colony.

Why doesn't the save show up in Load Game?

Steam Cloud is probably enabled, so the game reads from cloud_save_files. Copy the colony folder there or disable cloud saves.

What cycle is the colony on?

The colony is past cycle 1000 and fully stable, with no outstanding oxygen, food or heat problems.

About Oxygen Not Included

Oxygen Not Included is a colony survival simulation developed and published by Klei Entertainment, released in 2019. You manage a group of duplicants living inside an asteroid, keeping them supplied with oxygen, food, power and a livable temperature.

The game simulates gases, liquids, heat and pressure in detail, so every building choice has knock-on effects. Late game, colonies tap geysers and volcanoes, build steam turbines and launch rockets into space.

Building a fully stable, research-complete colony takes a lot of trial and error. This save gives you a working late-game base to study, expand or use as a sandbox for experiments.
