This is Vegas is an upcoming, third person action-adventure video game, featuring car chases and shootouts. The action is set in several major cities across the United States and takes place during a 48 hour period.

Development of the game began in 2003 at the now defunct Glasgow studios of Steel Monkeys. When Steel Monkeys in the UK shut down the game moved production to the secondary Steel Monkeys studio established in Minsk, Belarus.

Ign has posted some new info on this game, as well as a trailer. The screenshot pictured is from around 2005, when news first broke of the game.
This is Vegas is set for release on PlayStation 3, Xbox 360, and Windows this fall.
