Ikaruga

Ikaruga is a 2D vertical scrolling shooter made up of 3D sprites. Ikaruga is famous for its high paced action, its original shooter gameplay features and the massive amounts of projectiles on the screen.

In Ikaruga, you're the pilot of a vehicle that has the special ability to switch elements between white and black (light and dark). As one element, you're invincible from that same element while being able to deal double damage to an enemy of the opposite element. Thus by switching to the opposite element of an enemy you increase the difficulty of the game, the speed at which you can defeat your enemy and thus your overall score.
