Gyruss is an omnidirectional tube shooter wherein the player travels from Neptune to Earth. As in most shooters, things will shoot and be shot at.

It also beats Roc'n Rope by having not one but two members who left/were fired from Konami and eventually worked at Capcom. Oh well, I'm sure they didn't work on anything that successful after thi... Oh.

Unused Graphics

	A sphere with circling arcs of light. Is it an enemy? A powerup? A planet? Nobody knows.
	Graphics for 200- and 500-point bonuses (the used ones start at 1,000). The former is the score value associated with the satellites, while the latter is used when shooting the orange version of the unused sprite above.

Regional Differences

Centuri licensed Gyruss in the US, while Konami distributed the game elsewhere.

High Score List

Konami	Centuri

Centuri changed the top four names on the default high score list to their own. Makes sense.

Extra Life Settings

For whatever reason, Centuri increased the scores needed to get extra lives, making the game more difficult.

	Konami	Centuri
Easy	30,000; 90,000; every 60,000 after	50,000; 120,000; every 70,000 after
Hard	40,000; 110,000; every 70,000 after	60,000; 140,000; every 80,000 after
