This game is like a stripped down version of CoD. More realistic and down to earth with real war. There is no kill confirmation, no maps, no kill streaks, no life regeneration, and realistic gun shooting. The walls are not even bullet proof! It is one of the most realistic FPS games I have seen without being overly complex like ARMA is.
I am going to pick it up, likely later on today and give it a try. It has full controller support as well which is something I had an issue with CSGO. They also having realistic aiming and scopes which makes this game a strep above CSGO in my book. It is about 3 years old but still active online.
