''Gyruss'' was an arcade game developed and published by {{Konami}} in 1983. Gameplay is similar to ''{{Galaga}}'' in that you have to shoot down scores of enemy ships as they fly in and out of formation. However, the playing field is displayed in a ''{{Tempest}}''-like 3D perspective, allowing your ship to rotate a full 360 degrees.

It's probably best known for its in-game theme song, a remix of JohannSebastianBach's ''Music/ToccataAndFugueInDMinor''. (In stereo, no less!)

The game was ported to various Atari systems and the NintendoEntertainmentSystem (the latter in the US under Konami's subsidiary Ultra Games, and vastly different from the arcade version).

One of two games (the other was ''TimePilot'') that [[StreetFighter Yoshiki Okamoto]] developed with Konami before jumping ship to Capcom and making them famous.

!!Gyruss uses the following tropes:
* AdaptationExpansion: The NES version of the game has you flying from the outer planets toward the Sun, whereas the arcade game stopped your journey at Earth. It also has improved graphics, better music (and more songs), new types of enemies, bonus stages, super phaser shots, mini-bosses and bosses. In short: They Changed It Now It's ''Awesome''.
* BonusStage: Every fourth level.
* KonamiCode: The NES version had it, giving you a bunch of lives and super phaser shots. However, the twist is that you have to enter the code ''backward'' for it to work properly.
* RockMeAmadeus: A well-done remix of Bach's ''Toccata and Fugue in D-minor''.
* WordPureeTitle
* XMeetsY: ''{{Galaga}}'' meets ''{{Tempest}}''.
