PC Project Reality Team work Game

i use to play this game for about 3 years or more. Even if the graphic engine is to old, the inmersion and realism are brutal. You can play almost half hour lost in a big city, not shooting to anything and still feeling like you are there.
The comunity are very.. very involved with the game, and you will play real coop with positional audio. They use mumble.. an amazing speaking program that supports 100 player in one match with multiple sub-chanells for ecah squad with automatic asign. Amazing sounds... you will not beleabe it.
Is 100% free. An amazing game, really.
The only thing is, the graphic engine is to old.. for that reaqson the developers change to a new engine (uneral 4) and make a totally new game with exactly the same features and scenarios and everything, the name is SQUAD.
My recomendation.. try Project reallity.. if you like the game style.. buy SQUAD.. you will play only one game for at least 4 years.
