Attack on Titan 3 on Steam Deck

What is confirmed for Steam Deck

Steam lists full controller support for Attack on Titan 3 on the PC store page. Full controller support means the game works with gamepads out of the box — the same input path the Steam Deck relies on. That is the one confirmed piece of Deck-relevant information.

What is not confirmed

Full controller support alone does not prove Deck compatibility. These factors remain unannounced:

• Graphics presets — whether the Deck can hold playable frame rates at reasonable settings
• Resolution scaling — how the game behaves at 800p and 1280×800 native Deck resolution
• Proton compatibility — the game is Windows-only; it will run through Proton on the Deck's SteamOS
• Shader compilation — how long first-time loading takes on each map
• Battery life — power draw for the fast-paced ODM traversal
• Cloud saves — whether Steam Cloud sync carries your soldier between PC and Deck

What we can estimate from the series

The PC version of Attack on Titan 2: Final Battle ran acceptably on mid-range hardware, and the series has always shipped with a wide compatibility range. The ODM traversal is CPU-heavy — the game tracks anchor points, gas, momentum and dozens of Titans at once — so the Deck's APU may need modest settings (720p–800p, medium/low details, capped frame rate) to stay smooth during large Titan encounters. This is an estimate, not a promise.

How to check once the game ships

When the game releases December 10, 2026, the quickest way to confirm Deck performance is the Steam store page — Valve's official rating appears there. We will also fold community-verified settings and Proton reports into this page within 24 hours of release.

System requirements and the Deck

Official system requirements are still unpublished (Steam shows only "OS: TBD"). Our system requirements estimate gives a planning range. If the minimum CPU/GPU estimates hold, the Steam Deck's hardware sits roughly in the minimum-to-recommended band for this game type.
