Gorf
About
Gorf is an arcade game released in 1981 by Midway Manufacturing, whose name was advertised as an acronym for "Galactic Orbiting Robot Force". It is a fixed shooter with five distinct levels, the first of which is based on Space Invaders and another on Galaxian. The game makes heavy use of synthesized speech for the Gorfian robot which teases the player, powered by the Votrax speech chip. Gorf allows the player to buy 2 additional lives per quarter before starting the game, for a maximum of 7 lives.
