MUCH better than CoD5's "night of the living dead" map(s), this takes killing mindless zombies to the extremes of fun. Before I'd played it, I thought it would be an eerie horror shooter - thank god I was wrong!

The graphics suck. Suck suck suck. If you haven't played this yet, go fire up CS:S. There you go. Throw some zombies and less mind-numbing objectives into CS:S and you've got L4D, albeit better weapon models, maps and enemies. The physics are fun, once again thanks to Source, but still outdated and old. If you couldn't tell, I have no love for the Source engine. Show me Source 2.0 and I'll be more enthused.

The plot is also pretty unique, it's not a level that you're fighting through to survive - it's a movie. I guess that isn't really a plot, more of a theme, but whatever. Still, very unique.

Lastly, the achievements on the 360 rock. They're fun to attempt to earn, promising (potentially) hours of replayability for achievement and stat whores. They're also nothing short of stress relieving, or am I the only one who is calmed when I light 101 zombies on fire?
