Atic Atac is a top-down action game in which the player explores a castle with 200 rooms on 5 floors in an effort to collect the key of A.C.G. At the beginning of the game there are 3 character choices: the serf, the knight and the wizard. The main thing that separates the 3 classes is an ability to use different objects within a room as secret passages. During the adventure a player will come across various colored doors and would have to possess the corresponding colored key in order to use the door. Rooms of the castle are filled with a wide variety of monsters such as ghosts, bats, vampires, Frankenstein's monster and much more.
Atic Atac was developed by Ultimate Play the Game and released the back end of 1983 with the UK gaming press and gamers giving it a good reception. It was one of the thirty games included in the 2015 Xbox One compilation Rare Replay.
The ACG Key was so named because the original name of the developer was Ashby Computers & Graphics Ltd
