To earn the "WE ARE FREE" trophy in Detroit: Become Human, you must make sure that Kara and Alice get out of Todd's house alive in the chapter "STORMY NIGHT". It is possible to fail this, so it's best to keep things simple. This guide assumes you are playing on Casual difficulty; some QTEs may be more difficult if you are not.
*** Spoiler - click to reveal ***When cleaning Alice's room in "A NEW HOME" you will have ventilated her room, which unlocks a path out of her window. In "STORMY NIGHT", as soon as Alice runs upstairs and you gain control, move in any direction to receive an instruction to stop from Todd. Immediately attempt to move again. Press the button prompts to break free of your programming. Head straight upstairs, Todd doesn't notice unless you hang around for ages down here. Go straight to Alice's room at the back. After you've talked to her, opt to lock the door. Run and lock it. Head for the window and open it; don't stop to talk to Alice or Todd will break in! When prompted, commit to heading out of the window. When prompted again, Join Alice instead of Facing Todd. Mash when prompted.
Carry Alice and then slide down the pipe asap with when prompted. You'll land at the front of the house just as the bus pulls up. Run to it and the scene will end.
You'll receive the trophy when you reach the flowchart at the end of the chapter.
