I uploaded my map here in order for my friends to get a better look at it before using it on our hosted server. My friends and I worked on Mezaton City as a Tyeken's Test World before superflat mode was invented and I made heavy alterations (expanded it and added MezaCorp Tower) in Creative Mode and MCEdit during 1.2.5. I now copied Mezaton Isle and its spleef arena into the ocean off the coast of a huge mushroom island biome.
