Berzerk

Berzerk is a multidirectional shooter designed by Alan McNeil and released for arcades in 1980 by Stern Electronics of Chicago. Following Taito's Stratovox, it is one of the first arcade video games with speech synthesis. Berzerk places the player in a series of top-down, maze-like rooms containing armed robots. Home ports were published for the Atari 2600, Atari 5200, and Vectrex.

A sequel, Frenzy, was released in 1982.
