Instructions
Locate a vampire character. Players can find vampires in many places in Bridgeport; however, the Plasma 501 Lounge and the Brightmore Club seem to have a higher concentration of vampire characters than most other game areas. If a character the player has already befriended becomes a vampire, the character's box in the Relationship tab will begin to glow red.
Build a relationship with the vampire. Converse frequently, participate in activities together, or invite the vampire to your home. As you progress in your relationship, you will unlock additional actions and conversation options. Select positive dialogue options and actions until you befriend the vampire. You can view your progress in the relationship in your character's Relationship tab.
Request to become a vampire. When you have built a friendship with the vampire, the "Ask to Turn" option will appear in your conversation menu. Select it to allow the vampire to bite your character. Three days after the vampire bites your Sim, he or she will transform into a vampire. Sims who become vampires gain access to the following abilities: hunting, mind reading, enhanced speed and endurance, rapid skill acquisition, super strength and persuasion. However, there are also several drawbacks to Sim vampirism: vampires must stay out of sunlight to avoid burning and must feed regularly on plasma to prevent dying of thirst.
