FYI I just picked this up on the PC.

I hadn't planned to.... but then I got home and found my brother and one of my best mates online playing together and I caved.

10 minutes later I was playing with them and having an absolute blast. It's a little scary, but it's a lot of fun. I didn't play enough to give a proper review, but it's definitely the sort of game where the more you play it the more effective you'll be. Knowing what to do when one of your teammates is grabbed by a zombie is important!

Lots of fun and basically requires voice chat, so I may be getting another pair of headphones. Again...
