Ikaruga Sending It's Color-Changing Ship To XBLA
For non-Ikaruga fans, the game's core concept is that the color of your ship determines who can damage you. If your enemy is the same color as you, your enemy's attacks won't damage you (in fact you can absorb their attacks). And inversely, if you and your enemy are different colors, their attacks will damage you.This is where the color-changing aspect comes into play.
