I played Enlisted while I was on windows, there has been an officially released version of Enlisted for Linux (although it always ran on Linux) however that has been taken off. The original Enlisted ran but Linux players would get kicked by anti-cheat, does the original enlisted support Linux players that there has been an official steam release for it? If not will we ever get that support? Enlisted: Reinforced seems to be in limbo.
Afaik there will be Linux support when the Steam version re-releases.
