The Sims 3 Late Night gives players all-access to 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.
Players will be able to take their Sims into the bustling urban setting where they’ll be able to become local celebrities, members of music bands, mixologists, directors, and more. To gain entrance into the most elite clubs in town, Sims need to keep their attitude in check, otherwise they’ll be given the cold shoulder by tough bouncers -or they can find another way onto the list. If chilling is the player’s forte, their Sims can lounge at a chic club or dive bar. Or, if they like to live on the edge, they can discover the secret of becoming a vampire.

It was confirmed on July 20, 2010 at EA's Studio Showcase 2010. According to an official sneak peek at Late Night, it would offer players a more mature, realistic and urban environment when compared to earlier similar expansions. Previews of the expansion described it as being more about friend outings than dating and to be more simulation-driven instead of opportunity-driven as the first two expansionswere.
Late Night has been featured at a few real-life and internet events.
