Exciting news for FPS fans. The Arma 3 developers have updated everyone on what's happening with the Linux port, and it looks like they are even going to work on the BattlEye anti-cheat system.This is important because it means we would be able to play with everyone else, as we are limited to servers that don't use BattlEye.This is great news, as I was impressed by the performance of the port and was really hoping they would do this!For those who missed it, there is a Linux version of Arma 3 on Steam even though there's no SteamOS/Linux icon. They didn't know if they would be updating the port test to a newer version, but they now are which is great news.I still wouldn't suggest buying it until this big update is released, and think carefully if BattlEye doesn't get supported, as it's not a cheap game.Experience true combat gameplay in a massive military sandbox.
