when you've got three tangos shoulder to shoulder and shotgun aimed shells do nothing at point blank, except hit the snow directly behind them!
when you're running like a bat out of hell and can still snipe a tango 30m away with a snapped buckshot
when tangos can dance around a load of buck like Michael Jackson on stage
when hand guns are better short range weapons then a shotgun
when tangos are better dancers then shooters, are worse shooters then noobs, and more accurate then Hathcock, while sliding down a staircase backwards!
I could go on and on, but I'll just say Raven Shield demonstrates much brain damage.
