im posting this on behalf of mr noobler because he apparently lost access to his forums account
there isn't any brick pack required except for modter
the higher parts of the build have been blocked off with invisible baseplates, so there's no need to worry about zombies flying out of the map
he decided to upload this to the forums because there isn't much that could be done to lower the latency for other players in his server, so it could probably be modified to be a single player map or something else
feel free to criticize/judge the build
