Bungie has released a rather stern message on the official Help Page (https://help.bungie.net/hc/en-us/articles/360049024592-Destiny-2-Steam-Guide) for Destiny 2. The developer is warning players not to try and launch the game on the Steam Deck and news of this is slowly spreading amongst fans. Bungie states that “Destiny 2 is is not supported for play on the Steam Deck”.
The page notes that Destiny 2 isn’t supports for Steam Deck or “on any system utilizing Steam Play’s Proton unless Windows is installed and running”. Players who attempt to launch the game on the Steam Deck through the SteamOS or Proton “will be unable to enter the game and will be returned to their game library after a short time”.
While disappointing to many, fans are surprised to see that Bungie is threatening bans. The developer states that “players who attempt to bypass Destiny 2 incompatibility will be met with a game ban”. There has been no explanation provided by Bungie yet for the incompatibility or the ban threat.
