Gyruss 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 this game.

Anyway, 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.

Unused Graphics

Whoa, dude, look at the colors
A sphere with circling arcs of light. Is it an enemy? A power-up? A planet? Nobody knows.
You call that a bonus? While the point bonus of 200 is never displayed, it is the score value associated with the satellites. The 500 just beside it in the image is used when shooting the Orange-version of the unused sprite above. The bigger bonuses start at 1,000.

Regional Differences

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

High Score List

Konami Centuri
Konami OO Centuria?

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

Extra Life Settings

For whatever reason, Centuri saw fit to adjust the bonus life settings to make 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
