Recently, I highlighted that Bungie gave a very clear no to Destiny 2 on Steam Deck. Seems a lot of people noticed and Bungie has issued an update — but it's still a no for now.
In their This Week At Bungie blog post, they said they would provide "additional information" and went on to reiterate they wish to keep a "secure environment for Destiny 2", going on to remind people they teamed up with BattlEye (which supports Linux / Proton):
Our goal is to maintain a secure environment for Destiny 2, as it features both PvE and PvP combat in an evolving, dynamic world. Maintaining the integrity of our security is a complex and long-term process. In some cases it means teaming with partners like BattlEye and following their recommendations, in others, it means choosing to not support platforms that could provide bad actors with ways of compromising our own Bungie developed anti-cheat security systems.
Steam Deck continues to be an unsupported platform for Destiny 2, at least with SteamOS 3 Linux which it comes with out of the box. Their wording here is interesting though. It sounds like either BattlEye recommended against it, or they at Bungie specifically chose not to as they think Linux will somehow provide a way for these "bad actors" to compromise their game.
They did say they will continue to investigate but they have no other info. So really, they've not actually explained anything extra at all. How helpful.
Meanwhile, although no announcement has yet been made, Apex Legends continues working just fine on Steam Deck and Linux desktops with Proton as Easy Anti-Cheat now seems to be hooked up. No one from Valve or EA / Respawn has replied to my emails on it.
