This is a melee map. Yeah, you heard read it right. And no matter what it says above, it actually is 256x12. 5 bases each with 6 Vespene Geysers and 50 Mineral Fields, all with 50,000 resources each, is a terrific micromanagement practice map. It's also fun to see what people say when they realize that it's actually that size (you know, the novelty factor!). Have fun!
