Battlefield 6 is following the footsteps of Battlefield 2042 and other EA titles, requiring Secure Boot support. Discovered by Battlefield Wire on X, Battlefield 6's kernel-level Javelin anti-cheat system takes into account Secure Boot functionality and will prevent players from playing the game if the feature is turned off or not supported. At least the game will be easy to run on Windows PCs.
This requirement is not that serious for Windows users; however, it is very likely that Battlefield 6's Secure Boot requirement, in addition to Javel's kernel-level snooping, will prevent the game from working on Linux emulators such as Proton, killing Linux gaming support and Steam Deck support from the very start. Proton has no Secure Boot emulation as far as we are aware. (Even if it did, there's still little chance Javelin would work in Linux.)
