From FAQ:
What should I know about Linux support?
The new Epic Games Launcher runs natively on Linux, but many games are Windows-only builds and may need a compatibility layer. Check each game’s Linux compatibility before installing.
We support Ubuntu 22.04 LTS or newer, Fedora 43 or newer, and Debian 12 or newer. Other distributions may work but aren’t officially tested or supported.
Use the Send feedback button in the launcher to report issues.

Also epic is rebuilding Easy Anti-Cheat for Linux (EAC Linux v2) to deliver near-Windows-level protection using signed kernels, Secure Boot, TPM 2.0, and other existing Linux security features starting with a Fortnite, so more multiplayer games can finally support the platform without enabling widespread cheating.


TLDR for those who didn’t read the EAC Linux v2 post.
On hardware side, it requires TPM 2.0, Secure Boot and Input-Output Memory Management Unit (IOMMU) enabled in BIOS.
On software side, it requires a signed kernel and kernel modules, measured boot, kernel lockdown integrity mode, kexec to be disabled, and Linux Security Module BPF.
Where keys are needed, they must all be well-known. Epic maintains a list of well-known keys.
Basically this all requires that your machine has the required features and that your distribution provides a proper kernel.
It depends on systemd? I don’t care about init systems but watching the people who do is going to be very funny when it releases.
(I hate having to fiddle with my bios so I’ll probably stick to my switch for eac games but at least it isn’t a rootkit)
