Frenzy is an arcade maze/shooter from 1982 that was developed and published by Stern Electronics. It is the sequel to the 1980 arcade game, Berzerk, and features similar presentation and gameplay.
Konami‘s 1981 arcade classic, Amidar, is a maze game with a difference.
Released into arcades in 1980, Stern Electronics‘ Berzerk is a simple multi-directional shooter where the aim is to rack up as many points as possible by shooting robots in a maze.
Scramble was the first ever side-scrolling shoot ’em up, coming out in arcades in 1981.
It was certainly one of the earliest colour video games, and was a big hit for developer Konami and distributor Stern Electronics.
