This forum is for tips and trick to help gamers out that are having a little trouble with this game. I could be zombies, multiplayer or even custom classes. Map strategies are also recommended on this forum.
One thing I do if I'm shooting at somebody and they run behind a wall then I keep engaging doing a 3-6 round burst while moving towards cover but keep shooting the corner of the wall and generally they will poke their heads out to see what all the commotion is and there is you a headshot right there. Just be careful of the smart players who may try and flank you and don't do more than a 6 round burst or you will scare them or run outta ammo which gives them an opportunity to shoot you while you are out in the open.
I always run a class with emp grenades and engineer. It comes in handy when you are against a group that uses a lot of tacs, bettys or any other annoying equipment.
