A great tactical FPS.
As the leader of the team you can command the other members as you wish, this being done by a very easy to use engine. You can command them to duck behind a crate, or one of them to open a door and the second one to throw a grenade in real quick, to shoot certain targets, use certain weapons, mounted weapons etc.
Each of them is focused on a weapon or class. One is a sniper, medic and a couple more (i played the game a while ago i don`t quire remember all of them. you`ll figure them out as you play.)
A great game full of wonderful places, effects, voice acting and pure fun. I strongly recommend it to every fan of a good FPS or SW.
