This game has regional differences.
Gradius enters the bullet hell genre with Treasure at the helm.
Options vs Multiples
In a sort of callback to the renaming in the overseas Nemesis release of the first game in arcades, Options are called "Multiples" in the US and PAL releases of the game on the power meter and in the announcer voice clips.
For some bizarre reason, the PAL release uses a slightly stretched version of the font used for the Konami copyright on the title screen for score and menu text as well as the "Game Over" message.
|Japan and USA release||PAL|
In the Japanese release, O by default is bound to fire shot + missile while in both overseas releases it is bound to X.
