It's the not greatest game in the world but I like it, it's something new that my friends and I will enjoy.
The storyline is alright, I've encountered some annoying bugs that kind of detract from the fun. I also don't like being encouraged to throw my weapon because I generally miss and can't get it because it's down the street which is crawling with zombies lmao.
The co-op is fun, I mean you and your buds are killing zombies so you don't really mind the linear "delivery" boy type of missions.
I heard the PC got the best out of this game because of the stunning graphics and that the co-op match up is 10x better than the consoles.
If you have friends and want something fun, it's worth it.
