Following the recent Battlefield 6 multiplayer showcase that confirmed the existence of a UGC platform for the new shooter, EA's executive vice president, Vince Zampella, confirmed in an interview with PCGamesN that Battlefield 6 will not receive Steam Deck support. According to the executive, "It does not work on Steam Deck. I think there are some non-Steam-Deck handheld platforms that it will work on, probably, right? But I don't think, you know, it's probably not the best way to play the game."

This suggests that the reason for the lack of Steam Deck support comes down to incompatibility with SteamOS, rather than hardware limitations. The presumption is thus that Battlefield 6's EA anti-cheat still won't adopt Linux support. According to ProtonDB, 27% of Steam's current top 100 games work basically flawlessly with Valve's Proton compatibility layer, with an additional 52% receiving a "Gold" rating, which means the game runs basically perfectly using Proton with a little tweaking. Other gaming giants have also recently announced their intention to include Steam Deck and Linux compatibility in their upcoming titles, with Ubisoft being one notable example in recent months.
