Unlock Alternate Endings
At the begining of the game if you deplete Lucas' sanity bar in the restaurant he will be committed into an insane asylum.
Keep drinking the alcohol under the counter in the kitchen without taking the medication in the 'Lost Love' level and after the meter is depleted, Lucas will commit suicide by jumping off the balcony.
Get your meter as low as possible in the 'Confession' level and while talking with Marcus select the 'Sick' and 'Break Off' options and Lucas will turn himself in to the police.
If when Lucas is being questioned he does not have enough mental health, intentionally make mistakes a few times and you should be successful.
If you deplete Tyler's sanity meter, Tyler and Sam leave New York and go to Florida.
If you deplete Carla's sanity meter she will resign from the N.Y.P.D.
