Act IV - Will's Workshop 2010 | Walkthrough Quantum Break Guide

Follow Beth. You will hear a conversation between workers located downstairs. There is a lamp and a switch behind the wall - it's a Quantum Ripple so use it. That's the last one of them so if you were able to collect all eight of them, you will unlock Tossing Stones in a Pond.

Jump down and head left to get another Chronon Source. Get to the door.

Another laboratory is full of secrets

Follow Beth into the building. A bunch of secrets can be located in a single office: use the computer, listen to the recording from the radio, investigate a scheme on the desk and go behind the cabinet to find another Chronon Source.

A source is above the shed

You will be led to a locked door further in the hall. A vision from the past will take you to a small shed. There is a Chronon Source on the roof, and a large mock-up on the wall (secret) inside.

Use the switch on the wall to recreate the past and quickly get to the desk to use the device.

Pay attention to the board near Beth

Beth will let you know that the door was opened. Talk with her, but first check schemes on the board (last secret on this level). Prepare for another combat with Monarch troops. The fight will be relatively easy, as not a single special unit will appear. Just watch out for sharpshooters.

Kill them all and return to Beth, and end this part of the storyline. You have just unlocked Then We'll Die Finding Out.
