StarCraft/Enslavers
StarCraft Enslavers may be found in the Campaign directory of the Custom Maps database, and is considered a veteran level campaign not because of any inherent difficulty but because the missions are time-consuming. There are only five stages divided into two paths--the first instance of path splitting in StarCraft, since the only case in which the Episodic campaigns use path splitting comes in Brood War's Emperor's Fall.
Enslavers follows the hunt for the 'second-rate smuggler' Alan (Allen) Schezar, who has managed to establish multiple extensive bases as well as gain control over a Cerebrate. The question of whether to aid the Protoss being held captive by Schezar or to kill the Cerebrate results in a split path. In (a), players ignore the Protoss plea and kill the cerebrate, leading to the last level's Protoss and Terran enemies. In (b), players save the Protoss instead, leading to the last level's Zerg and Terran enemies. The (b) path provides players with Protoss allies in addition to the Terran forces, but also adds in the Ultralisk hero Torrasque, which is periodically ressurected. Both paths have a trick in the last level: in (a), destruction of the Protoss Temple will prevent the Protoss enemies from Warping In additional units, while in (b), destruction of the Zerg Cerebrate will prevent the return of Torrasque.
