noob....its crap at level 49..if you want to get far you need the ray gun, browning,mg42,flamethrower.......all these guns(by doing the glitch) will get you to round 49, the only way you will lose at this level(because the zombies no longer come in the windows) is if you quit.oh yeah and the ptrs it gets headshots with 1 bullet from like 1 -35
