Epic Games’ anti-cheat team is rebuilding its Linux protection as Easy Anti-Cheat Linux v2 to bring Linux game security closer to Windows parity and enable more multiplayer titles (Fortnite will be piloted first). The move responds to a booming commercial cheat industry that can ruin player bases; the plan combines engagement with distribution maintainers and community leaders, a public well-known key list, and a co-hosted panel with Fedora leadership to align ecosystem practices. Deployment will be opt-in per game, developers can keep the older implementation for compatibility, and Epic invites distro maintainers to add signing keys so fewer players must change setups.

EAC Linux v2 avoids a persistent kernel driver and instead uses platform features plus eBPF and a systemd service that runs only while protected games run. Required protections include a signed kernel and signed kernel modules, TPM 2.0 enabled, Secure Boot with well-known keys, measured boot, IOMMU enabled, kernel lockdown integrity mode, kexec disabled, and the BPF LSM active. Players can maintain separate boot entries or enroll their own keys (with guidance about MOK vs db), and failing requirements produces an error rather than an automatic ban. Steam Deck lacks required features today but discussions with Valve are ongoing.
