i find that if people jump on a banister, and cant stand up straight, they crouch, then i shoot them, they kinda go higher, lol its kinda funny as they just float there, and die.
I've heard glitches like this on other forums.
It's due to a total rush by the game makers.
They had to release it by Nov 19. So as a result bugs and bad camera angles.
I haven't tried the game yet. That's just what I've read.
