The Gates of Aku is the only stage in Unleashing the Cats , which appears after clearing all three "Wicked" maps: Wicked Cat , Wicked Tank and Wicked Axe . Once cleared, it disappears permanently.
Despite having no rewards of its own, beating this stage is required to access most stages that feature the Aku Altar base, which is indicated by the message "Aku Altars Appear! Your Aku Research is complete and the Gates of Aku have opened! Visit Empire of Cats to enter this dark realm..."
