1UP Review: Geometry Wars: Retro Evolved 2

1UP writes: How do you make a worthy sequel to a $5 twin-stick shooter that single-handedly defined the Xbox Live Arcade service and ensnared a generation of Achievement junkies? Other Geometry Wars games -- like Waves and Galaxies -- came and went, but none managed to repeat the same lightning-in-a-bottle brilliance of the original Geometry Wars: Retro Evolved. Long anticipated, Retro Evolved 2 tries its hand at packing in as much content as possible and re-creating the magic of its predecessor.
