Its not the old Amiga helicopter game. Its based on Desert Strike for SC1. Desert Strike was probably the most popular tug of war map for SC1 since it came out. Specifically "version Queen" by Queen-Gambit was very popular. I've based mine on that version. Much to my pleasure, Queen-Gambit commented on my project, and seemed to be quite pleased with it.
The patch messed some things up (lots of things :s), but I'm working on fixing them. :)
