I am looking for the name of a old game. It was a space shooter game with extremely basic graphics. The aliens were very similar to the space invader aliens. (all pixels) The screen did not move or scroll like other games, and the aliens came in from all sides. You were NOT stuck on the bottom like space invaders and galaga. It was free movement with the arrow keys. When you shot some of the aliens the would drop life.. or points.. ?? and I mean this was a VERY basic game. all black background. Almost no graphics what so ever besides the aliens and ship. Help Please!!???
