3 players share the top of the map, while 3 players share the bottom of the map. It is an all out shared bases war, WITH HEREOS. There is a store in the middle left of the map where you can use minerals/gas to buy heroes(Kerigan, Jim Raynor, ...etc). You must use your regular starcraft army, along with your heroes, to kill all that are on the opposite side of the map. Very fun/challenging map. :-)
