Crystallis is a multiplayer map for StarCraft: Brood War. It supports two players.
Huge portions of the map are covered with a forest of low yield mineral patches (all patches have 48 units) which prevent early game harassment. Continuous mining is required not only to acquire vespene gas but to open a path to the opponent.
Terran players (and to a certain degree zerg since they need to build lots of hatcheries anyway) have an advantage regarding mining, since they can lift off their command center and move it whenever a batch of minerals is depleted.
Melee units are only useful when a lot of transporters are available or most of the minerals have been removed so the emphasis should be put on air and long ranged units (siege tanks).
