good luck finding it. I went to about 10 stores, and found it at Walmart. Best game I've played in awhile. Feels like FallOut in how you get assigned tasks, build XP, and have to maintain weapons. Most of the weaponry is melee based. More fun anyways. Story is actually decent to this point. I've only played for an hour or two. It's intense because a weapon will break half way through a fight and you have to find/arm yourself with another.
It is first person based, driving is odd, but I'm pretty sure it's based in Australia, or close to it. Its a ton of fun, and there are some intense moments. I've found myself fighting off 10 or more zombies at a time sometimes. I'd pick up a copy.
