A gameplay trailer for the Resident Evil 6/Left 4 Dead 2 crossover has come to light. Consisting entirely of in game footage, it showcases the four playable characters from the latter kicking ass and taking names in the former. But that's not all. The last half minute or so reveal yet more surprises. There are also at least two of the Left 4 Dead enemies now in the Resi 6 Mercenaries mode as well. The Witch and the 'mini' Tank. This, I must confess, is beginning to show a most welcome trend from Capcom. Keep it up chaps, and you might just win us back. Comments below.
