I rented it. I beat the game in about 4 hours. Its not really hard, but its fun. A few glaring problems though. Umm the graphics are crap, the levels sometimes are a bore. Ex. the jungle parts.... umm hit detections is crap. I shot a guy about 5 times in the body with the sniper rifle before he died and also some head shots dont work.
Its good for a rental, but other than that, its pretty shitty.
Its not as good as Allied Assult.
