Activision have deployed an update to the icon issue that saw PC players being shown as Xbox console players after the MW3 Game Pass launch.
MW3 and Warzone saw a huge spike in cheater reports since the Game Pass launch on July 24, and to make matters worse, PC Game Pass players were showing up with the Xbox console icon.
This confused many as players thought they were facing off against fellow console users, but were actually challenging PC Game Pass players, some of which would have been on mouse and keyboard. It made hackers harder to spot, which led to the devs quickly responding with an update to their detection system.
As of July 30, Activision have released an update to fix the issue and confirmed that PC players via the Game Pass will now show up with the correct icon.
