What are some cool tactical shooters? I know that Linux has some good shooters like Xonotic, but I would like something more tactical like Arma, Rainbow Six Siege or CS:GO. It doesnt have to be open source altho this is a big plus. I know about AssaultCube and Urban Terror, but they seem unmaintained/dead.
AFAIK, the game will boot but the BattlEye anticheat (or lack thereof) will prevent you from actually joining an online raid. And the offline raids don’t allow for any progression. You might be able to play the Single player mod of Tarkov with this though.
