Zombie Attack!

This is my very first map and i am trying hard to make it get real big and good :D as much as it should be a challange it also should be possible the map is compatible with singleplayer and multiplayer you can play it alone or with some friends i am stil working on it and once i am done with the rooms and redstone ill start making it look very nice hopefully you all will like this as much as i enjoyed making it :) if you wish to try this map with others or even just test it befor playing you can always look up one of my servers were i have it online for testing hope you have fun playing on it :D
