Changes where beams and snipers appear to strike without affecting target selection. This means that fake spores could be created that appear to dramatically arc through the air without the need for players to put all their beam towers at the top of the map.

Offset is measured in pixels, there is eight pixels to a square. positive is in the up direction.
