I’m amazed it even works on linux, guess there is one benefit of using some shady unknown Korean kernel level anticheat instead of EAC.
EAC does work on Linux, developers just have to flip a toggle switch to support Linux. Some devs just don’t want to do that.
Halo MCC, Apex Legends, Back 4 blood, and Smite are all games that use EAC and work on Linux.
And basically no kernel anticheat will work on Linux. So Helldivers 2 isn’t kernel anticheat, just user-space.
Helldivers 2’s anti-cheat (nProtect GameGuard) is kernel-level on Windows, but has a userspace fallback for linux
Edit: see this post
And the anti cheat functions in user space! No special permissions required.
