Gridrunner is a fixed shooter video game written by Jeff Minter and published by Llamasoft for the VIC-20 in 1982.

Many remakes and sequels have followed, including versions for the Atari ST, Amiga, Pocket PC, Microsoft Windows, and iOS.

[6] In 1984, The Commodore 64 Home Companion advised to "forget the plot; fast action is the name of this game".

[7] In 1983, Minter released Matrix: Gridrunner 2, which retained much of the original's gameplay, but introduced new enemy types and a scrolling background.

Featuring retro sprite-based visuals and faster-paced gameplay on a scrolling field, it proved popular with fans.

Originally developed under the working title Gridrunner+++ it was released on Windows PCs as Gridrunner Revolution, after a newly introduced rotation mechanic.

This version also made heavy use of Minter's "light synth" tech, with colorful, psychedelic visuals.
