Developer ITEM42 recently announced DEFICIT and it's not often I feel I really need a game after seeing a trailer but DEFICIT looks juicy. Not a whole lot has been revealed just yet since it's a fresh announcement. But you will need Proton to play it on Linux, SteamOS and Steam Deck.
From the Steam page:
Designation: [Carrie]. Location: [Project Sidereal].
Assignment: under the instruction of your shady benefactor known only as [The Client], you must steal the [Interpolator] and use it to escape the sprawling research labs of Project Sidereal.
Project Sidereal is housed within Hadrian's Wall, a maze of concrete warrens and liminal installations policed by the seasoned officers of the Oversight Taskforce.
Sneak past them, turn their defensive systems against them or take them head-on: the best path through the manifold dangers of Project Sidereal is yours to choose.
Check out the announcement trailer from January 10th:
Direct Link
Features:
- Single-player campaign FPS with an emphasis on chaotic close-quarters combat, creatively lethal tools and environmental havoc
- Exploration: take the direct route or find the path less travelled through the warrens of Hadrian's Wall
- Open wormholes to terrifying frontier realities on valid surfaces to navigate otherwise impassable liminal spaces
- Face a medley of adversaries: haphazard Oversight Officers, ruthlessly precise Servitor mechanoids and frangible UAVs
- Hammers, screwdrivers, paintcans, bricks, batons, pistols, SMGs: any item makes for a tremendous weapon in the hands of a skilled freelancer
