Gekirindan[b] is a 1995 vertically scrolling shooter arcade video game originally developed and published by Taito in Japan, America and Europe.

Headed by Snow Bros. and Twin Hawk composer Osamu Ōta, Gekirindan was created by some members of Toaplan at Taito after the former company declared bankruptcy in 1994.

Gekirindan is a science fiction-themed vertically scrolling shoot 'em up game reminiscent of Truxton II and DonPachi, where players assume the role of one of the six pilots taking control of their respective space fighter craft (a futuristic fighter jet, a helicopter conditioned for space travel and a remodeled old-fashioned airplane) through five increasingly difficult levels in an effort to effort to defeat Huge Boss and prevent his plan of rewriting human history as the main objective.

Similar to DonPachi, players also have the ability to choose between three fighter ship types, each having their own shot pattern: A, B and C.[2][3] There are multiple scoring methods for reaching high-scores to obtain extra lives in the game apart from destroying enemies.

The only resistance Huge Boss faces is a group of six fighter pilots from multiple eras who aim to stop him, although some of them have their own motivations other than saving mankind.

[5][6][7][8] Snow Bros. and Twin Hawk composer Osamu Ōta acted as producer under the alias "Lee", while Hidetomo Ogino was the project's sole designer.

[6][7] In a 2007 forum post at French website SHMUP, unused sprites from the unreleased Toaplan arcade game Dynamic Trial 7 were discovered to be hidden in Gekirindan's code by a community member.
