Taken from the game's files and optimized and prepared for FDM 3D Printing.
Abductors hover over certain places and... kind of just stay put. But only for a little while. After some time, it’ll send beams at the ground, taking away those who decide to walk in them. Some who claim to have been abducted say they were taken to the Mothership, but we don’t know what the Aliens would have to gain. Why let people see the Mothership then bring them back home?
