Twinbrook

Twinbrook is a new town which will ship with The Sims 3: Ambitions.

Description
In an interview, Grant Rodiek mentioned Twinbrook, saying;

"The town of Twinbrook is absolutely beautiful and designed specifically for players. You will clearly see how our world-designing team has improved when you discover Twinbrook."

Twinbrook will most likely stress the new careers and skills introduced in Ambitions, such as the Stylist career or Inventing skill.

According to a Gamespot hands-on, Twinbrook 'is a fictitious bayou town not unlike a backwoods suburb of Louisiana.' Players who attended the UK hands on event report that Twinbrook 'is a huge new town, which had been flooded (if I read the town description correctly this morning), and is now half-swamp half-town. The swampy areas are very dank and misty. The other side of Twinbrook has brand new shops such as the Laundromat, The tattoo parlour and stylist shop and much more. I really enjoyed having a look around Twinbrook, and the place looks really great. They've also re-done most of the rabbit holes, such as the diner.'

It is also known, due to a group of leaked images from the game, that the town depicted in the second trailer is in fact Twinbrook.

It may be assumed that Simslaus Creek refrences Stanislaus County, a county located in California or the Stanislaus River located in the mentioned county.
