Why don't you visit Moon City Backup! It has the lot, a building map as big as possible, thousands of lava levels (coming soon), and even thousands of zombie levels (as you may know when you see it all, they're identical.) An IRC is coming soon, and it's even been prepared for you a bit! (Due to my router's firewall, which I have now disabled so you recognise the server. (Blue portal goes to main level, lava goes to guest.) If you have a look at our zombie server, you'll have loads of things, including an identical main map! (With no portals, just beach and hotel so you can relax! (Pay 30 pounds for the hotel.)) It's got the lot. And now to our SPECIAL OFFER! You get Operator rank PERMEMENTLY! Hurry up, this offer ends 29th September 2013!
