The Last Cerebrate
Take command of Zthezj, a powerful Zergling hero, and his hive cluster in order to defeat the invading Purifier army before they can destroy your wounded Cerebrate.
This is a standalone scenario map with a light story, modified Zerg, Terran, and Protoss factions, minor in-game unit customization choices, adjustable difficulty, and more. Typical run time I think is about 30 to 60 minutes.
