Easy Anti Cheat blocks playing this otherwise flawless title.
Starting a Sortie fails with a "Inappropriate actions have been detected. Returning to Title Screen. (Error Code: EAC-EOS_ACCAR_NullClient-0)" message. Loading to a Sortie in progress (including one that was terminated on startup by the EAC NullClient message) allows for approximately 60 seconds of normal game play before terminating the session with another "Inappropriate actions have been detected. Returning to Title Screen. (Error Code: EAC-EOS_ACCAR_AuthenticationFailed-0)" message. The game's traditional death penalties apply if you die due being kicked out by anti-cheat.
This report was written during Season 2 at the tail end of June 2025. I requested a refund shortly after purchase due to Easy Anti Cheat blocking all progress within the game after a certain point.

The game has become unplayable as of the recent Season 2 update for linux and steam deck users.
PROTON_ENABLE_WAYLAND=1 %command%
nullclient error from EAC
The game has become virtually unplayable as of the Season 2 update for Linux and Steam Deck users. As EAC is no implemented correctly still, it frequently puts out a nullclient error. Upon this error it sends you back to the main menu, you can go back into game after but you will be sent back to the main menu upon trying to go back in, or get into the game and play for a minute before the nullclient error happens again, kicking you back out to main menu. As of now the game is unplayable.

The Game runs fine. There is a error message when starting about EAC failing but despite that it runs.
On Steam says it has Kernel Level Anticheat. But it seems to be integrated wrong or something. you can still play the game completely fine.

Steam now updated the store page to include:
Uses Kernel Level Anti-Cheat Easy Anti-Cheat - Requires manual removal after game uninstall
so that's a disappointment

Generally small UI
Runs well with minor hitches on the Favor Performance preset.

Played a few sorties, everything went smoothly. Set to 'Prioritize Graphics'. EAC error on sortie but does not seem to have any effects.
Works well, multiplayer included, despite EAC error 'Inappropriate actions have been detected. (Error CodeEAC-EOS ACCCAR NullClient-0)'. With all graphic settings on high It is running well enough for my purposes, usually between 50 and 100 FPS with occasional frame drops. Unfortunately, no ultra wide support (not OS-specific).
Experienced some initial slowdowns on connecting to the multiplayer session

Probably not due to the fact that cutscenes don't get rendered in and multiplayer issues.
Can't access multiplayer and cutscenes don't get rendered in.
Some stutters here and there, but that can be attributed to graphical settings.
Can't actually play once in open world multiplayer sessions, game crashes very quickly
