The title says it all, and I have played my fair share of zombie games (ranging from fps's like COD to action games like a few XBA titles. And Dead Space, if you can call those zombies).
It has almost everything you can think of: managing resources, finding resources, running from hoards and chucking a grenade behind you for a satisfying *bang*, and even decent driving physics (just don't drive into a juggernaut...)
I have yet to play the DLC, but I plan on it...
