Grid Defender is a very high graphic arcade TDS with many unlockables and awards.
Basic controls are:
WASD to move.
Left click to fire.
Right click to use a bomb.
Spacebar to toggle grid (Saves FPS).
Thanks to Elijah Lucian, Navij11 (www.navij11.com) and rig(www.rigaudio.com) for the music and sounds.
By the way, YOU CAN MOVE. (Thank you very much for making me do that people on the YYG forums.)
