50/50 chance this breaks Deck and linux support, especially since the commenters’ inquiries about it have gone unanswered.
Bogles my mind why a PvE game needs an anti-cheat at all - let alone something as invasive as a rootkit.

EAC is honestly pretty standard at this point for multiplayer games. It’s used by some really big companies like Epic for Fortnight, Mihoyo for Genshin Impact (iirc), and obviously Elden Ring. I couldn’t find anything reputable saying it is a rootkit, just that it reads and monitors kernel-level processes.
Whatever Helldivers is doing is something else.
