I finished the game and got bored so I opened an old game and made myself invincible. I would like to continue to play this saved game, but want to undo the cheat. Anyone?
Well, if you used the console, just type in the cheat again. Other than that, I suppose you could play with the variables...but without a Shadowkeeper-like program, I wouldn't know how.
If nothing we do matters, then all that matters is what we do.
