How to Become a Vampire in The Sims 2 Without Cheats

Vampires are a life state first introduced in The Sims 2: Nightlife, where they are both playable and non-playable creatures.

They have bluish-gray skin, red eyes, and fangs.

Vampirism is transmitted via the bite neck interaction performed by a Sim who is already a vampire, such as a Grand Vampire, who will initially only bite Sims with whom they have a high relationship; however, once the Grand Vampire has bitten a Sim, their likelihood of biting other (playable or unplayable) Sims is increased until the lot is reloaded. Non-Grand Vampire Sims still require a high relationship in order to successfully bite another Sim. Other Sims can also Influence a vampire to bite another Sim, though it will likely be successful only if it is a Grand Vampire that is influenced to do so.
