Some information on the map: Marine Swarm is a 6-player custom game. There are two teams of 3 players each. Every 20 seconds, every player will receive Marine reinforcements. Each player can also choose a Hero to help the army. Hero units have special abilities and are primarily used to capture important regions "King-of-the-Hill" style. Players earn minerals by holding regions and killing opposing Heroes; Minerals can then be exchanged for Mercenaries or Upgrades.
