Q: Where are Oxygen Not Included saves on Linux?

In ~/.config/unity3d/Klei/Oxygen Not Included/save_files/.

Klei’s space colony sim has run natively on Linux since 2017, through 1.0, every DLC and a move to Unity 6.3. It is Steam Deck Verified and single-player, so there is no server to host. Here is how it scores, where your colonies live and what developers can learn from Klei. Updated November 2026. Part of our Linux games list.

02Tests

How it does on our four tests

03Setup

Installing and requirements

Buy and install on Steam. The native Linux build is used automatically.

	Minimum	Recommended
OS	Ubuntu 22.04 or later	Ubuntu 24.04 or later
CPU	Dual core 2 GHz	Intel Core i7-8700K or equivalent
RAM	8 GB	16 GB
GPU	Intel HD 4600 or AMD/NVIDIA equivalent	Dedicated card with 2 GB VRAM
Disk	3 GB	3 GB

Big late-game colonies lean hard on the CPU, so the recommended specs matter more as your base grows.

04Deck

On the Steam Deck

Valve rates it Verified, with full gamepad controls and the native Linux runtime. Single-player needs no internet connection, so it is a good game for travel.

If the game crashes at launch on your distribution, one Linux player’s fix was to force the older Steam Linux Runtime 1.0 in Properties, then Compatibility.
