Unlock all levels cheat

A lot of websites[1] claim that entering "J8OL14FD" as log-in name will unlock all levels and sequences. However, from the large amount of people who appear to have been unsuccessful at trying to use this cheat[1], it seems to be a fake.

Alternate endings

  • Deplete Lucas' sanity bar in the restaurant when the game starts. He will

then be committed into an insane asylum.

  • In the "Lost Love" level, keep drinking the alcohol under the counter in

the kitchen, without taking the medication. After the meter is depleted, Lucas will commit suicide by jumping off the balcony.

  • In the "Confession" level, get your meter as low as possible. While talking

with Marcus, select the "Sick" and "Break Off" options and Lucas will turn himself in to the police.

  • Deplete Carla's sanity meter and she will resign from the NYPD.
  • Deplete Tyler's sanity meter. Tyler and Sam leave New York and go to Florida.

Lucas being questioned

If you are stuck at the point where Lucas is being questioned and do not have enough mental health, intentionally do it wrong a few times and you should succeed.

Omikron The Nomad Soul reference

Early in the game when you wake up as Tyler, there is a desk in the bedroom with an action figure. Examine it, and he will say "This is a figurine of Sox, a character from my favorite videogame." Sox is a robot from another game by Quantic Dream, Omikron The Nomad Soul.
