good game. Should make a sequel. But should have more physic damaging things i.e. barrels that do damage when flung into enemies (not exploding) or falling damage.
Things i know that N00bs should know too (and some veterans): 1. Surround a Boss. If you are shooting it from 5 different directions at once it will be confused about who to attack. 2. Don't snatch and grab. If you grab a health pack and someone else needed it before you they die then you die and the game is ruined. (finally) 3. The games F%^&%#$ about TEAMWORK. If you don't work together you all DIE! Thanx.
