In the fall of 1982, Tandy published the game as a TRS-80 CoCo ROM cartridge labeled Microbes, with no visible change from Meteoroids for the Dragon, except the title screen. The packaging and manual, however, rigorously translate the space premise to a medical one: asteroids are microbes, flying saucers are "X-Factors," and your ship is a "Disinfector," miniaturized and inserted into the blood stream through the miracles of modern medicine. The Disinfector shoots antibiotics, while the X-Factors shoot antibodies. Hyperspace works the same, except in Microbes it's called invisibility, even as the manual acknowledges the side-effect of random relocation.
