Drift

Drift is a single player, freeware, Asteroids variant. The game is entirely keyboard controlled and is slightly unusual in that firing the gun causes the ship to move in the opposite direction.

The story behind the game runs as follows "*The year is 5300 and you are in command of the brand new experimental DriftRunner V3X22 (yep... a major improvement over the old V2X22 series). Humanity has colonized huge parts of the galaxy but the mysterious Vhol Drift has never been successfully explored. Strange aliens with strange technology live inside the dangerous Drift and it is said that he who successfully explores the Drift will be both famous and rich.

So, your mission is clear. Enter the Vhol Drift and try to penetrate as deep as you can. But beware... the asteroid field gets more dense the further you go and encounters with the evil Polygunzz are also more likely. You have to shoot and destroy all the asteroids (and other obstacles) to clear a path through the Vhol Drift to make it possible for Terran exploration crafts to enter the Drift and exploit its resources and discover its mysteries. The task will not be easy but if anyone can do it, it surely is you...*"
