Atic Atac is a 1983 action-adventure game developed by Ashby Computers and Graphics Ltd., released for the ZX Spectrum and BBC Microcomputer System. Set inside a sprawling castle, the game tasks the player with locating the Golden Key of ACG while navigating a network of rooms, unlocking doors, and evading a variety of enemies that roam the environment. The game was notable at the time of its release for requiring 48K of RAM on the Spectrum, making it one of the developer's earliest titles to demand the expanded memory configuration rather than the standard 16K found in unexpanded models. The game later received renewed attention when it was included in the Rare Replay Collection, a retrospective compilation released for Xbox One.
