A new leaked Left 4 Dead 2 Zombie Survival Guide trailer has surfaced and it shows off the brutality the new melee weapons are going to bring.

A Swedish site has posted a leaked Left 4 Dead 2 trailer onto YouTube. The trailer doesn't show us any new game footage but it is jam packed full of cinematic carnage. We get a good look at how brutal the new melee weapons will be when they are used on the undead. We also get to check out all four survivors talking tough and kicking zombie ass. The rumors floating around is that this might be the intro movie to the game. That was my first thought when I saw the leaked trailer. It would make a lot of sense since it looks like each of the campaigns is represented in the trailer as well.

You can pre-order Left 4 Dead 2 now and gain early access to the demo or wait for it to be released on November 17th for Xbox 360 and PC. Check out the leaked L4D2 trailer after the break. It is definitely NSFW though.
