This is an idea I had a while ago for my new server called Craftopia City Apocolypse. I thought it would be cool to have a portal to another world thats a zombie-survival/challenge map. You start out in an old bomb shelter in the mountains outside of town. The sky is completely blacked out and I filled in all the space under the city so mob spawn is extra high above ground. There are also Zombie spawners placed at every intersection and at the main entrances of the buildings and stores.There are about 15 treasures hidden throughout the city at all the main locations for players to try to fight thier way to.

This isn't really a new creation since all i did was edit the main city on my server, but I still thought it was a fun idea to show everyone. I'll have a Schematic up for it pretty soon :P
