Valve Software just can’t seem to keep the lid on these things!  The intro cinematic for Left 4 Dead 2 has leaked on to… *gasp* …the internet. The game is the sequel to Valve’s extremely popular co-op zombie shooter Left 4 Dead.

I think it’s a sneaky way to get publicity, but it works right?  After all, I posted it and you just watched it. You win this round Gabe Newell!

If the innumerable hours I spent playing the original Left 4 Dead are any indication, I’ll be spending quite a bit of time with L4D2 this winter. And if the trailer didn’t whet your appetite for the game, you can expect new characters, new campaigns, new modes, new weapons (chainsaws!), and new zombie types for the sequel.

Left 4 Dead 2 hits the PC and Xbox 360 on November 17th.
