XIGNCODE3 anti-cheat working towards Steam Deck support by launch

By - | Views: 24,308

XIGNCODE3 is another popular anti-cheat like Easy Anti-Cheat and BattlEye that currently causes issues for Linux and it's going to hopefully see support (thanks Reddit) for Linux and the Steam Deck by launch.

Developed by Wellbia, XIGNCODE3 protects something around 272 titles according to their website although that appears to be spread across PC, mobile and consoles.

What games specifically use XIGNCODE3? That's actually not all that easy to find out, as Wellbia don't list the games specifically. Black Desert Online did previously use it but that switched over to Easy Anti-Cheat. Games that do use XIGNCODE3 that we've been able to find include Aion, Blade & Soul, DJMAX RESPECT V, Knight Online and the upcoming ELYON.

It's not exactly surprising to suddenly see more vendors look to support Linux either through native builds or Proton, since we know the Steam Deck has a lot of excitement around it. Since it uses SteamOS 3 (based on Arch Linux), any anti-cheat will likely need to be updated for it.

We've sent off a message to Wellbia to see if we can find out more information.

Another one down!
Very good to see all these anti-cheat companies jump onboard for Linux/Steam Deck support.

Quite! After so many companies got cold feet following the Steam Machines not panning out, it’s a relief to see the industry still willing to go along with Valve on this new approach :)

at least they didn't say developers have to enable it, hopefully those games just work when they do their adjustments.

Indeed! Who knows, maybe Valve soon will as well!

The list of Steam games using XIGNCODE3 can be found on SteamDB:

It was possible to list them using PCGW as well here: but for some reason it stopped working

EDIT: Turned out it was caused by SemanticMediaWiki being problematic and getting phased out in favor of Cargo; here's the proper page listing all XIGNCODE3 games on PCGW:

i would get excited but we saw this movie before, and the last time it was more exciting...
game engines were the ones who started supporting linux, but the marketshare didnt moved an inch, we get just a few AAA native games, the number of AAA decreassed over time and some games stop working after a few time due to linux breaking backward compatibility or if the game was something with constant updates, the linux marketshare wasnt worth it.

steam deck can change it since it has an higher demmand, lets hope story dont repeat itselft, but let keep our expectations in check.
