Zombie Adventure Pack

I'm creating a zombie map pack. I have two maps that are both being close to be finished. It will have 4 maps. The first is a prison. The second is a WWII Trench map and a mining system. When it is finished, it will be for sale for server use, but is FREE for solo and/or local server use. It will also come with skins to be played with. Stayed tuned for updates! Check outhttp://www.youtube.com/user/MrSpyman101for early gameplay!
UPDATE:
-WWII map named~Dawn of the War
-Dawn of the War is now ready for beta
-Prison map is almost done and still is un-named
