Exterminator is an action game developed and published by Premier Technology and Gottlieb. It was also released for PC, Amiga, Atari ST, Amstrad CPC, ZX Spectrum and C64. You are a pest control exterminator who is just a giant disembodied hand, and you need to clean the houses of a street off pests. Each house has several rooms. You take out one room at a time. Each room consists of single screen. Pests will come forward from the back wall of the room towards you. If you kill a pest, a tile will become red (or blue in case of player 2) on the floor. If you manage to fill a line of tiles from the foreground to the back wall, you finish the room.
