I'll send you the PM since it can be pretty difficult at first, at least if you don't know what you're doing. Once you realize what needs to be done then it's super easy, just a bit long. One thing really nice about this map is that as you get the things, the Maxis voice lets you know you have it all. Also the end reward and music are awesome.
Though, I gotta ask, is there any way you guys can make it so that it's possible to play the song again and again. It works so fucking well in this map. Honestly this is an insanely cool map, though I hate the train tracks more than anything else in the known universe.
