Just wanted to say that Left 4 Dead reminds me of an older set of games called Hunter, and Hunter: Reckoning. Believe it was a PS2 title, third person shooter based around multi-player co-op. Seemed quite similar from what was mentioned in the vid anyway. Zombies, magic powers, big ass guns... the typical co-op shoot the monster and run style game.
Will have to see more on the game, but so far doesn't seem like a Valve style title (don't mean that in a bad way, just quite off from what they normally seem to focus on. Which isn't a bad thing btw). Be interesting to see how it is.
I love how 90% of the time I click on your review/disscussion videos they never load properly. They'll load 10sec into the (contracted?) MS commercial and stop...and of course I click play like an idiot which takes me directly to the MS website...nice way to bump up your hits and charge MS more while screwing the little guy who just want to watch a video.
