From the start - my very first 'tag-take' kill was in a game of Seine rush where a guy rounded a corner near the first set of MComms and I panicked and knifed him from the front.
Good thing you are panic prone :-D.
btw. who here is from EU and plays BF3 on PS3. I am now desperatly seeking friends to play BF3. I am tired of playing with randoms.
