Gyruss

Gyruss (ジャイラス, Jairasu) is a 1983 tube shooter video game developed and published by Konami for Japanese arcades. It was initially licensed to Centuri in North America for dedicated machines before Konami released their own self-distributed conversion kits for the game. Parker Brothers released ports for the Atari 2600, Atari 5200, Atari 8-bit computers, ColecoVision and Commodore 64 in 1984. An enhanced version for the Famicom Disk System was released in 1988, followed by the Nintendo Entertainment System in 1989. The gameplay is similar to that of Galaga, albeit in a tube shooter format, with the player's ship able to move around the perimeter of an implicit circle.
