Slap Fight

Slap Fight, also known as Alcon in North America, is a 1986 vertically scrolling shooter developed by Toaplan and published by Taito. Initially an arcade video game, it was ported to home systems by third-party developers. Set on the colonized fictional planet of Theron in the future, where an alien race led by Gaudy have invaded the human-controlled location, players assume the role of an Allied League of Cosmic Nations (ALCON) fighter pilot taking control of the SW475 space fighter craft in an effort to counterattack the invaders.

Slap Fight proved to be popular with arcade players despite a low number of arcade boards manufactured in Japan, but was met with mixed reception from video game magazines across western regions, specifically the home conversions. Although it never received a direct sequel, the game's ideas and weapon system were later inherited by both Truxton and Grind Stormer, with the latter being regarded as its spiritual successor. The rights to the title are owned by Tatsujin, a Japanese company formed by Masahiro Yuge.
