Konami released Gradius in Japanese arcades in May 1985; at launch its official Japanese title was 超次空ファイター グラディウス. Outside Japan the arcade game was called Nemesis. It was directed by Hiroyasu Machiguchi, with music by Miki Higashino, and the player pilots the Vic Viper starfighter. The Moai enemies pay homage to Xevious and the Nazca Lines.
The Famicom version followed in Japan on 25 April 1986 and reached North America as Gradius in December. It is where the famous Konami Code began: a pause-screen cheat that grants nearly all power-ups. In the Famicom version the ending messages change over six loops and spell out "KONAMI" when read in order.
Gradius was ported widely, from the MSX, with an extra stage, to the X68000, where it came bundled with the first model, and the PC Engine, which added a Desert Planet stage.12
