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.
The game was ported to various Atari systems and the Nintendo Entertainment System (the latter in the US under Konami's subsidiary Ultra Games, and vastly different from the arcade version).
Gyruss uses the following tropes:
- Adaptation Expansion: 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.
- Beethoven Was an Alien Spy: According to the backstory given in the instruction manual for the NES release, these aliens are led by Genghis Khan. How did he get there?
- Bonus Stage: Every fourth level.
- Konami Code: 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.
- Rock Me, Amadeus!: A well-done remix of Bach's Toccata and Fugue in D-minor.
