this game is horrible, genetics lab proves it. would never have had the patience for if it wasn't for the badge. It sucks because i like most of the thing things... this one is just terrible and frustrating, however
The doors only opening after a certain # of kills is a cheap way to make the game challenging. Also, it's really irritating that the enemies shoot right through eachother, what am i supposed to do for defense when im in a cramped room with 5 guys shooting at me who I can't even shoot back at?
