Your Sims can turn themselves into a werewolf through a bite from another werewolf
However, there are also werewolf families whose offspring are then automatically werewolves
Werewolves can be created in Create a Sim mode
There are also werewolf-specific life events
Sims can embrace or fight against their werewolf existence
Werewolves can live in packs, or your Sims can make it through life as a lone wolf
There are so many pictures within the trailer that showcase the new Occult Type (Werewolves), the new World, Build Objects, Interactions and adventures of a Sim going through self-discovery and acceptance as an Occult.
