I'll be honest, I've played through 3 campaigns with my friend on co-op on the 360, and I am hopelessly addicted, it is such a riot (literally) and I love it when you're attacked by 100's of em, + the addition special zombies make for interesting and sometimes thrilling fights, it's always fun to set a tank on fire and watch it run riot
. My personal favorite is in the farmhouse, hiding out in a tiny windowless room with my mate awaiting rescue while killing zombies by the hundred, never gets old
.
I have to say that there are little or no glitches/bugs to speak of on the console version, not that I noticed anyway and I'm usually pretty good at spotting these things, perhaps the PC version wasn't as rigorously tested, but I don't know.
Cheers, Decky.
