Steam Deck Verified (September 17, 2026)

The badge

Eleven days before launch, Valve marked the game Steam Deck Verified — the highest of Valve’s three compatibility ratings. The announcement links Valve’s Verified landing page for the game, where the badge is displayed alongside what it covers.

The developer’s own note: they have been “a huge fan of the Steam Deck since it was announced”, it is their favourite way to play games — “and that makes it of course my favourite way to play AVS03.”

What Verified means in practice

Verified is Valve’s assessment, not the developer’s: the game runs natively on SteamOS, displays and reads text correctly on the Deck’s screen, uses the controller scheme out of the box and supports the Deck’s features. The Steam Deck guide breaks down the rating tiers, and the system requirements page lists the full-game specs alongside it — the spec bar is low enough that Deck-class hardware clears it comfortably.
