Epic Games developing EAC Linux v2 to bring Fortnite to Linux
Epic Games is building a new anti-cheat system for Linux using eBPF and secure boot tools to enable native compatibility for titles like Fortnite.
Summary
Epic Games has announced plans for EAC Linux v2, a new anti-cheat system designed to work on Linux without requiring a Windows-style kernel driver. The system will be tested first with Fortnite and relies on existing OS security features like eBPF and TPM 2.0. While this could bring major multiplayer titles to Linux, current requirements may pose challenges for users with custom kernels or Steam Deck hardware.
Technical requirements for EAC Linux v2
- Uses eBPF and BPF LSM to monitor game memory and detect cheats.
- Requires Secure Boot with trusted keys and a signed kernel/drivers.
- Mandates TPM 2.0, measured boot, and IOMMU (on non-handheld PCs).
- Requires kernel lockdown in integrity mode and kexec to be disabled.
- Operates via a small system service that runs only during protected game sessions.
Why it matters
The move could significantly expand the library of playable multiplayer games on Linux, though strict security requirements may limit compatibility for users with highly customized distributions or Steam Deck hardware.
What to do
- If you use a custom kernel or self-signed drivers, be aware these may fail EAC Linux v2 checks; Epic plans to work with major distros like Ubuntu, Fedora, and Debian on trusted keys.
- Steam Deck users should note that the device currently lacks features required for EAC Linux v2, so Fortnite support on Steam Deck is not ready yet and remains under discussion with Valve.
- Watch for Epic's first Fortnite test of EAC Linux v2, which has no firm release date yet, and a planned public talk with Fedora's Jef Spaleta later this year.
