The gameplay co... See morensists of shooting enemies who come in one of two polarities: either black or white (sometimes called red or blue). The player's ship can be either polarity, and can be switched at will. Treasure previously experimented with colors and polarity in the title Silhouette Mirage, released for both the Sega Saturn and the PlayStation.
Ikaruga's gameplay centers primarily around the polarity mechanic. Only bullets of an opposite polarity can kill the player. Same-color bullets are absorbed and converted into energy for the game's special weapon, a homing laser. Switching the ship's polarity also changes the color of the ship's bullets, and shooting an enemy using opposite-polarity bullets will cause double damage. Thus, much of the challenge of Ikaruga comes from careful polarity-switching, choosing between high damage and (relative) invulnerability. This is especially true when fighting bosses, as they often fire bullets of both colors in overlapping patterns. The game also presents navigational challenges where the player must maneuver through continual streams of weapons fire, using their shields to absorb one color while avoiding the others.
