I played in for a short time on PC, got bored, I got lvl 55 in a day and then it just gets crap.
Though I do wish they would bring back BEL gametype from COD1.
1 Player has to hide and the others have to find and kill him, they are given a rough location on the radar, with gillie this might just be the best gametype ever, if you kill him you get to hide next aswell.
