Description: [Xbox Live Arcade] Treasure's award-winning scrolling shooter brings a tactical twist to the genre with its yin-and-yang gameplay: the color of your ship determines your effect on enemies. In this polarized system, enemy ships and their bullets are one of two colors. Attack an enemy of the opposite color for extra damage. Absorb enemy fire of the same color as your ship, and use the energy for a special attack. Destroy multiple enemies of the same color to score a chaining bonus. Play solo or cooperatively, and use your polarity to achieve victory. Multiplayer support for two-player co-op offline or over Xbox LIVE allows you to clear the levels with a friend. [Treasure]
