You have to experience getting your limbs cut off by a light saber, being set on fire, lying on the shore near lava for however long and then being taken off to Palpatine's lab where you're fitted with prosthetics and placed in the suit. You're completely awake for all of it.
Once it's over you're restored to original condition. Your limbs return, your wounds are healed and you get a million dollars.
