Making its way from Xbox Live! to a more portable means, Geometry Wars: Retro Evolved Mobile was originally a hidden mini-game unlocked in Gotham Racing 2. Beginning each level with three lives and three "smart bombs," players must navigate their claw-shaped spacecraft through a variety of obstacles and enemies in order to clear the level and earn as many points as possible. Gamers can either avoid hazards or face them head on with unlimited machine guns that are upgraded with every 10,000 points earned. ~ Gracie Leach, All Game Guide
