Unsupported but playable
Steam Deck games Valve says don't work — but actually do
Valve's Unsupported label doesn't always mean what you think. Some games are flagged for anti-cheat systems that only block online play — the single-player campaign runs without a hitch. Others are marked for "performance issues" that the ProtonDB community has never actually experienced.
These 11 games carry Valve's Unsupported badge, yet have Gold or Platinum status on ProtonDB — confirmed by thousands of real Steam Deck players. Judge for yourself.
