Start with non-productive buildings, which you must defend or lose, and supply depots. Get a constant automatic stream of units. Kill units to get more powerful units. Destroy 2 buildings to get SCVs (up to 4) to build buildings yourself (for free). Massively fun on 4v4 - way more than in 3v3!
Each team has two terran players, a zerg player, and a protoss player. A full team is essential for teamwork and balance.

250 kills - Firebat
500 kills - Jim Raynor (vulture)
750 kills - Kerrigan
