Gyruss is a shoot ' em up arcade game that was developed by the Japanese game maker Konami and released in 1983. In the U.S., the game from the company Centuri was expelled. The game has similarities with Tempest and Galaga. The game requires three different microprocessors: two Z80 microprocessor and 6809 and, in addition, an Intel 8039 microcontroller. For the sound five - AY 3-8910 PSG sound chips and a DAC were used.
Game play is similar to that of Galaga. The player controls a spaceship and trying different formations of enemy spaceships shoot. Unlike in the game Space Invaders also solve a single opponent from this formation and approach the player's spaceship.
The effect is similar to the game Tempest. A simple 3-D effect is achieved by the game is shown with the aid of an imaginary cylinder. The player's gaze is directed into this cylinder. The spacecraft can move around the outermost line of the base. Another game that uses a similar effect is BlockOut as a 3D implementation of Tetris.
Unusually for games with 3D effect this time, Gyruss is no longer represented by a vector (see Tempest ), but with raster graphics.
The game consists of 24 levels, of which six represent a bonus round. Every four levels describe a trip to the planet Neptune, Uranus, Saturn, Jupiter, Mars and the Earth. Interestingly, the really first level, the first part of flight to Neptune, the last level in the game dar. So the game gets unlike other endless games, a player can be perceived by reference to the repetition of the entire game.
For the soundtrack, a synthesizer version of the Toccata and Fugue in D minor, BWV 565 was chosen. This is based on a cover version and hit single of the band Sky, which was released in 1980. Also unusual for arcade games of the early 80s is playing the music in stereo.
The game was released in 1984 for Atari 800, Atari 2600, Atari 5200, Commodore 64 and ColecoVision. 1988 was followed by a slightly modified version for NES.
