FPS with experience driven character building done right.
Another really rewarding point is speccing your character out. It is alot of of fun as your character gets better. The only thing missing is for female players of the game (i am assuming there are some) there is only a male gender option.
The vehicles are well integrated as mobile spawn points and the overall combat as not about blindly running and gunning. So if that is what you are looking for look elsewhere (you will get owned in this game with that mindset by squads of people). The sniping is really fun, and watchng streams of bullets fly about with no lag is an awesome effect as you are running into battle.
Overall it's an FPS so don't expect anything different. But the elements it adds to it, and how they play out is alot of fun.
I give it an A- overall.
