Portal:Fallout: New Vegas
According to J.E. Sawyer, its name is derived from the fact that players referred to it as "That Gun from Fallout and Fallout 2".
The game takes place in 2281, four years after the events of Fallout 3, and thirty-nine years after Fallout 2. The Courier, the player's character, is meant to deliver a package from Primm to New Vegas. However, the Courier is intercepted by the Great Khans and Benny, who leave the Courier for dead in a shallow grave.
