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.
Act I length and the post-game loop
The official EA FAQ estimates roughly 12–15 hours for Act I. Launch reviews report about 15–30 hours depending on exploration, reading and side content. After the current story endpoint, Guild Hall repeatable Dungeons and Bosses, Deeds, Bounties, Stronghold, Pets, relationships and gear collection become the main loop; the Race/Class updates planned before Act II are roadmap context, not current content.
Launch input workarounds
Support for controller and Steam Deck does not guarantee every menu is stable. Launch reports mention controller conversations that may need keyboard and mouse; an older developer reply describes Z → Talk / Trade for NPC interaction. Keep these as version 0.107.x troubleshooting notes and re-check the current prompt after each Hotfix.
