Critical Annihilation - Mass destructive Voxels!
Critical Annihilation by Devoga is an action packed free Voxel game with plenty of firepower and rocket propelled explosions. Although not a final release and a test of the engine, it is awesome to the core as you kill enemies and watch their bloody gibblets splatter all over the ground. The game also features some of the best voxel explosions I've seen especially after a rocket attack.
Originally titled "Critical Mass", Critical Annihilation although free in downloadable form or played through your browser does need a more modern PC. On my boot camp PC it was unplayable but others have found the game to be very enjoyable. If the game is running slow, try lowering settings in the video settings menu. You can access it by pressing <escape> in game.
