ALF had a video game for the Sega in 1989.
The game is a side-scroller with the object of controlling ALF as he goes around town attempting to retrieve the items he needs to repair his spaceship, so he can join his Melmacian friends in outer space. For some unknown reason, this requires him to use a salami to fend away the bats in an underground cave. The game was released on the SEGA Master System.
