if you think that ones hard, try to get the "only one who hasnt died in a map" one. now thats really impossible...
//edit: i get what youre sayin, but that arch is even harder and bugged as well. we even tested it.
pretty much EVERY fuckin time you press 1/2.... it bugs the skin and youre screwed. and then most of the times you cant turn it off and youre stuck either with reconnectin or tryin it again next map. its gettin really annoying.
