Brass Balls Help.
hey guys im going to play through Bioshock a second time to get Brass Balls achievement but i had a few questions i wanted to clear up first.
can i still play on easy then change the difficulty to hard during the boss battle & still unlock the achievement?
how do you disable the vita chambers? do i have to start up a game then turn them off in the options or is there a way to do it in the main menu before you start a new game?
also do i have to do a play through in one sitting in order to get this achievement or can i save & come back to it as i want?
