From the WTF?! dept...
A games developer named Zach Gage has created a game
where the enemies are created based on files on your hard drive and killing the enemy permanently erases the corresponding file.
The game aims to raise questions about whether having the power to kill something means that you should necessarily use it and Gage himself says that "Although touching aliens will cause the player to lose the game, and killing aliens awards points, the aliens will never actually fire at the player". The whole concept seems to be aimed at making the gamer question why they are killing if they have no actual aim.
The game can be found here http://www.stfj.net/art/2009/loselose/
for anybody that's interested but play at your own risk.
