If you try to bypass compatibility checks.
The Steam Deck is upon us, and Deckers may be wondering whether their newly purchased handheld will be able to play everyone’s favorite shooter Destiny 2. The short answer is no, with the long answer being no and if you try to bypass compatibility checks you’re probably going to get banned.
Bungie updated their Steam guide this week with information that Destiny 2 is not playable on Steam Deck, unless you install Windows on it first. Further, any attempt to bypass that compatibility check will be met with a game ban.
Destiny 2 is not supported for play on the Steam Deck or on any system utilizing Steam Play’s Proton unless Windows is installed and running. Players who attempt to launch Destiny 2 on the Steam Deck through SteamOS or Proton will be unable to enter the game and will be returned to their game library after a short time.
Players who attempt to bypass Destiny 2 incompatibility will be met with a game ban.
The compatibility issue is due to BattlEye anti-cheat. Keen observers will note however that in January Valve announced that adding Deck support for BattlEye games was now a simple process and that the anti-cheat was “easily supported” on Steam Deck.
