Island of the Insane is a Use Map Settings co-op map for 4 players in StarCraft: Retribution. This map is similar to A Brief History of Yugoslavia, but works in the opposite direction. The player's team surrounds a computer Insane Difficulty force (protoss and zerg) on the island, but they have anti-rush protection with photon cannons and sunken colonies. This map is recommended by WizardWorks for beginners.
