The mod is timed to mark the anniversary of the attacks of 11 September 11, 2001.
The complex consists of 2 towers and a hotel. Located in Las Venturase.
You need to go to the Casino of Caligula and then to the yellow marker near the elevator. And further on the markers. When moving on to the handle of the screen will be black for about 1-2 minutes. Do not worry, the mod work, you just need to wait. There is the restaurant Windows on the world that is located on the 107-floor in the North Tower.
