Oxygen Not Included from Klei Entertainment is a brilliant building sim and it's getting some Steam Deck improvements.
Going over some of their plans for further additions to ONI, Klei put up a roadmap on Steam that sounds pretty great. There's both technical improvements and free content planned, including "support for Steam Deck in the coming weeks". They did just recently fix an issue with the random generation in the native Linux build too. They didn't go into specifics on the Steam Deck changes but it's likely gamepad input support which would be the big one.
On top of that there's also plans for performance improvements, bug fixes and the free content planned for both the base game and the Spaced Out expansion. They teased the free upgrade could include "quirky new Duplicants, new critter morphs, and fresh decor and recreation buildings, all designed to expand opportunities for expressive gameplay".
Some of the ideas we’re exploring for this free content pack include quirky new Duplicants, new critter morphs, and fresh decor and recreation buildings, all designed to expand opportunities for expressive gameplay. This should hopefully be out by the Summer.
