Additionally, Dead Money was first hinted via in-game graffiti. The textures for these graffiti are in a folder in the game files called "nvdlcgraffiti", and all the textures share the filename "nvgraffitisierra". Interestingly, this folder contains a number of other textures, sharing the filename "nvgraffitihonesthearts". These read:

    "Where's New Canaan, anyway?"
    "The Burned Man Walks!"
    "Joshua Graham Lives!"

This implies that one of the future add-ons will be titled Honest Hearts and will feature Joshua Graham, Caesar's former right hand, who is also known as the Burned Man, as he was set on fire and thrown into the Grand Canyon for his defeat during the First Battle of Hoover Dam. New Canaan is another location that was originally meant to appear in Van Buren - a Mormon town that Graham originally came from.​
