I'm playing online coop Campaign on Insane level with 3 friends of mine. In many situations, the better weapon is the Butcher's Cleaver.
But after some enemy kills, a bug / glicht happens: the screens turn to a dark / red color, the camera angle drastic changes and I bleed out until I die. If any of my team mates uses the Butcher's Cleaver, the same problem happens.
Maybe, my problem partially have a connection with this another one:
Thanks for any help you could give and sorry about my english.
PS: It's a shame the developers don't fixes bugs like this! :-(
