With this videogame generation being inundated with First Person Shooters, it's pretty much a given that developers have to add an extra something to spice up the experience some. That's what Valve's done with Left 4 Dead(Xbox 360, PC), giving the game not only convincing characters, stellar voice acting, team-based gameplay and a very tense soundtrack, but also zombies.

Lots of zombies.

And that's exactly what we see here in this video gameplay update of the squad-based shooter. Left 4 Dead takes what you thought you knew about the walking undead and literally throws it out the window - much like a certain zombie shooter from Capcom did. Featuring not only fast-moving zombies that not only attacked in swarms, the title also features different types of the undead - one in particular that barfs out blood.

The gameplay here is quite intense, fast-paced and very edge-on-your-seat stuff, what with the characters spouting lines that really humanize their struggle. And of course, the zombies themselves, attacking everything and everyone in sight.
