Ghosts have arrived in The Sims 4. Get a first look in this official trailer. Ghosts, how do they work? Just how do you find these spooky creatures from the spirit world? When a Sim dies, non-player character (NPC) ghosts attach to a tombstone or urn around your Sim’s home or yard.

But these aren’t just decorations. You can build relationships with these ghosts, and invite them to join your Sim’s household where they can become playable characters. Once a ghost is “playable” it can get a job, get married and contribute to the family like any living Sim. Of course, they wouldn’t be properly undead without some special ghostly abilities and behaviors.

The way you play determines ghost behavior as well. If you keep your ghost Sims happy they’ll be a big help around the house freeing Sims to spend time working on goals, making friends or whatever it is that makes them happy. For example, you may hate how long it takes normal Sims to repair objects around the home.

With ghosts around you can use “ghostly repair” to save all kinds of time! A Ghost Sim can even be used as a sort of maid that tidies up while your Sim family sleeps if the Ghost Sim has the “neat” trait.
