I've played Dead Money a few times already, and I have no idea how to get Dean Domino to live in the end. Every play-though I do, I end up killing him in the end because he is fearful of me killing him if he gives me the key to the theater. Can ANYONE give me a step by step instruction on how to get Dean Domino to live in the end? Maybe from entering the Sierra Madre and getting knocked out to meeting him at the stairs in the stage at in his theater. PLEASE a STEP by STEP process on how to spare Dean Domino!!!!!

All I know is that you've got to not try to take control of any situation. Don't let on that you're intelligent at all.
