Following in the well-trod footsteps of games like Geometry Wars and Robotron 2084, ZunderFury is a hardcore arena shooter that is happiest when it's overwhelming you with throngs of spiky blob-things. You can even spend money in between rounds to upgrade your ship, and the game comes with a full set of Xbox Live-style achievements, called "Feats", which is a smart way to personalize and flesh out the experience.
