The Photachyon Transceiver is a device invented by Keen that allows one to, as the official story states it, "point to anywhere in the galaxy and you can pick up a signal as if you were right there." The device is mentioned in Keen 4 for the first time, and the only time so far. It is an important element in the story, as through it Keen picks up a signal from which he learns that the Shikadi are planning to remake the galaxy in the name of the Gannalech!
