Revenge Note is a paper note in Fallout: New Vegas. It can be found on the hostile gambler during the quest Birds of a Feather. The gambler is encountered when you are guarding the doors to the Silver Rush.
To whom it may concern,
If you are reading this, then I am likely dead. I can only hope that I have managed to take out some of those thrice-damned Van Graffs with me. My family deserves that much, at least.
- Picking up this note (as in, searching the dead body) may break the quest, as it interrupts the "help me clean this body up" phrase that Simon says. However the body ends up in a nearby dumpster and the note can be collected there.
