EA announces The Sims 3: Late Night, the next expansion pack for the lifestyle simulation. The new expansion, which requires the original game, allows you to go out and party the night away, in that virtual sense of course. Word is: "The Sims 3 Late Night gives players all-access and lets them loose on a vibrant, active downtown scene where they’ll rub elbows with celebrities at the hottest parties, hit the local bar after work, tour the scene with their Sims’ band, kick back in a plush hot tub, and discover what’s lurking as the lights go out and adventure begins after dark." The announcement comes with some screenshots and a teaser trailer, which is embedded below.
