SC2Mapster

Maximum of 7 players. One player (the base commander) builds and expands melee-style while the other players support/defend him with a few units each in order to defeat a large Zerg group. Available squads include Defense, Support, Tanker, Stealth, Artillery, Infantry, and Versatility.

Map A is the original, a fairly small-sized map.
Map B is a larger map with less linearity.
Map C is about the same size as Map B.
All three maps are unique, so if you like one, try the others.

All of these maps are published in North America.
