Geometry Wars 3: Dimensions

Drive a small ship through a three dimensional grid filled with various kinds of enemies. Your aim is to shoot down the different shapes and evade the oncoming ones. Once you touch them, your ship is destroyed and a life is lost.

Dimensions features over 100 levels with 12 battle modes. Survive long enough and set a high score. Each time you shoot down the shapes you gain a multiplier which keeps increasing until you crash.
