I decided to edit this review because the game has changed.

They have added quite a few amount of features since the last update, although it is rarely updated, it does get updated with new features. It now has local co-op so more then one person can play on the same computer, new barricade design and more.

Pros:
Controller Support
Deathmatch (I have yet to play this but it seems interesting.)
endless night(You can't build or get new guns, really proves a challenge)
Local Co-Op (not many games have this)
Cons
Gets boring after a bit

Overall:
This game is a little bit fun, for the price. it goes on sale a lot and is worth it when you play with your friends. I managed to reach wave 20 with me and my friend, it's worth it now with the new update
