4 Fun In One was produced by Armenia in 1981. This multi-game system lets you select from four different bootlegs that resemble Centipede, Defender, Galaxian, and Pac-Man. They are: 1. Galactic Convey (an arcade game like Centipede with Galaxian mixied) 2. Scramble Part 2 3. Galaxian Part 5 (more like an updated/tweeked version of the original Galaxian than a sequel) 4. The Ghost Muncher Part 3 (more like a clone version of Pac-Man and an update to Ghost Muncher)
