Welcome to BioShock Answers. What would you like to know?

If the player does not attack Mr Cohen in Fort Frolic, they will be able to gain access to a secret area in his living quarters; later on in the game in Olympus Heights which in turn will give them access to an otherwise unattainable Power to the People vending machine.

To gain entry to Sander Cohen’s apartment, simply disrupt the two dancing Houdini Splicers in his apartment. Then he will then come down to kill the player, thus opening the previously locked door to the second floor of his apartment. You may then kill Sander Cohen and retrieve his key to the Muse Box in Fort Frolic.
