Take control of one of five Terran factions - Raynor's Raiders, the UED, Terran Dominion, Umojan Protectorate or the Terran Confederacy and battle for multiplayer supremacy.
Raynor's Raiders can construct Protoss Warp Gates, which allow you to instantaneously travel between two points. The portal will remain open as long as the Warp Gate's energy reserves hold out, or until cancelled.
