I accidentally discovered a way to "cheat" through Dead Money. The "cheat" I discovered is that if you download Courier's Stash while playing Dead Money all of the equipment you would normally receive at the beginning of the game from Courier's Stash you receive during Dead Money. So if you are at the beginning of Dead Money and you download Courier's Stash instead of just having the basic Dead Money equipment you will also have all of the armor and weapons from Courier's Stash in your inventory. I don't know if this has been discovered before, but I just decided I'd let anybody having troubles with Dead Money know.
P.S. I know this isn't really a cheat but I didn't know what else to call it.
