DiggKiller: The Game is a clever use of the Digg API that turns the site into a space shooter game.
By shooting at the enemy (Or is it bury?), you decrease its Digg score until it reaches zero and explodes in a shower of good and bad comments.
You then collect these comments for an increase in weapon power, as well as a few power-ups that are triggered by certain comment keywords.
Additional weapons include the Rose Bomb and the F-Bomb, and there are plenty of surprises in store during the later levels.
