Supported is the starting point; a useful Steam Deck guide needs measured performance and input behavior from the current build.
Platform and input
The source confirms PC / Steam, keyboard and mouse support, gamepad support and Steam Deck support. Steam feature tags include full controller support and Xbox / PlayStation controller support.
Co-op boundaries
The public frame is solo play or online co-op for up to eight players using peer-to-peer hosting. No local split-screen is confirmed, and the host's World owns story, buildings and recruited allies.
Steam features
The source records Steam Cloud, Achievements, Stats and Family Sharing as platform-facing features. Treat them as support facts, while save migration and version behavior still need current-client checks.
What to test on Steam Deck
The official support statement is not a performance review. Verify frame pacing, UI scale, controller glyphs, inventory drag behavior, crafting station navigation and skill-tree readability on the EA build before publishing a preset recommendation.
