The Sims 4: Get to Work is the first time that aliens make their probing comeback to The Sims. You will need this expansion in order to get abducted, first and foremost. Once you do, you’ll be ready for some freaky nights.
Abductions happen randomly at night, mainly between 9:00 PM and 4:00 AM. Both male and female sims can be abducted, and once they return they will have a moodlet pertaining to this experience. However, males have the chance of coming back pregnant with an alien baby.
Looking through a telescope, being a scientist, having the satellite dish, having the worm hole generator, and using the satellite dish all increase the odds that your sim will be abducted. You are also allowed to visit the alien home planet and have some fun with some aliens, by the way, if you have the rocket ship.
