UFOs

UFOs are similar to Scouge except they can move. They only change directions at Walls, Empty Tiles, Boxes, Pits and Enemies. UFOs can't be given directions to turn when they collide with something; they do so automatically. If a Stinker is on any tile north, south, east or west of it, it will shoot Fireballs at that Stinker. 4 UFOs each are generated by Motherships if all of the UFOs present in the level get destroyed.
