InfiniteSims caught the fact that GamesRadar was able to reach EA PR representative Angie Newman for more clarity on Vampires appearing in The Sims 3 Late Night.  Here’s what she said:

“You have to find a vampire in the world, befriend it, and then ask it to turn you into a vampire. You can then turn other Sims into vampires,” explains Newman. Late Night also includes a new Blood Line system, which will let you pass your vampirism onto your offspring. “So if a vampire and a vampire mate, it will for sure be a vampire baby. But if a vampire and a non-vampire mate, it might be a vampire or it might be a Sim. There’s no half-vampire, half-Sim babies.”

And what will you feed on once you’ve become a creature of the night? “They quench their thirst by eating plasma packs, drinking plasma from other Sims, or growing rare and awesome plasma fruits.”
