Never ones to shy away from a bit of publicity, at a Valve Left 4 Dead 2 event held today in London, passers by got a little more than they bargained for.

Well, a couple of guys dressed up as zombies seems appropriate, but they can also be a little disconcerting when chasing people down the street. The event was held to promote Valves latest shooter, despite a vigorous out cry from the community it’s looking to be delivering a quality experience and makes some interesting improvements over the original.

Expect to see a full hands-on preview in X360 very soon!
