In 1981, Bill Hogue wrote Robot Attack, a variation on the arcade game Berzerk. Unlike most TRS‑80 games, in Robot Attack you can move and fire in all directions. You fire in a direction by moving the joystick in that direction and pressing the FIRE button.
In October 1981, Alpha Products created a new version of their joystick which included a mode switch to allow a choice between the STICK-80 and TRISSTICK FIRE button behavior. The advertisements from then on referred to the joystick as the Alpha Joystick, and the price remained at $39.95.
