Grid Defender 2 is a great arena shooter with neon graphics that is inspired by Geometry Wars. Shoot your way through hordes of enemies and earn money by destroying them. With the collected money you can buy different weapons, upgrades and unlock two new game modes. You can also get some extra cash when you master some Achievements. A really good and fast paced shooter!
From the Homepage:
This is a fast paced space TDS much alike asteroids or geometry wars. It features two different modes of gameplay, a customizable ship, and many different enemy types.

The FX look absolutely awesome, but when the grid warps with the player it seems pretty obnoxious. Other than that, it looks very nice.
