Act V - Monarch HQ | Walkthrough Quantum Break Guide
Last update: 03 June 2016
You will encounter Monarch troops at the very beginning. There will be some agents and one armored opponent, so take cover when possible. You will find the first secret, radio, in front of the stairs, at the reception.
Get through the door opened by Fiona/Charlie (depending on your decision in Junction 4: Surrender - Charlie, Control - Fiona), and turn left. There is a Chronon Source above the door to the men's bathroom. Check the map of the building and go upstairs.
There are three secrets on the desk- Intel is one of them. Two enemies will come after you but they shouldn't be much of a threat. Get to the elevator and head to the top floor. Take the tablet from the sofa and open the door.
First take down three enemies at the door (sneak up on them from behind and use Time Blast), Expect three agents and two Juggernauts. Pick up ammo from backpacks that are scattered all around the area. You will also come across two secrets: a board by the window and a laptop on one of the desks.
Pass through the door and turn left to enter a dark office. Take two secrets from the desk in the corner, and a Chronon Source which is situated on the right, next to the entrance. There is a paperweight (Intel) in the corridor. There is also a computer with secrets few meters away.
Use your navigator to find a tablet on the desk behind the next door and Serene's computer in front (pick it up after the cut scene). Walk along the wall and collect a tablet from the cabinet. The second one (Intel) is on the bed, and if you look behind it, you will find the last Chronon Source.
Walk downstairs and collect a secret from the laptop which is situated next to sketchbook. Head to a secret passage hidden in a wall. Enter the laboratory and check the laptop.
At the end of the hallway, behind the door, you will stumble upon Liam Burke who wants to stop you - although this happens only if you've selected the Surrender option during Junction 4. Otherwise, regular guards will be in the area. He will try to stop you but he is not a supper-boss. Although, you won't be able to use your abilities, Liam is not that good with guns and few bullets should be enough to take him down.
Finish the battle and pick two more secrets (laptops). They are situated at both ends of the room. Use the door and you will find a tablet on your left and Charlie's ID on the right, on the floor (Intel). That was the last Intel and if you were able to find all the pieces, you will unlock Knowledge Is Power.
Pick up the Countermeasure that you have been searching for. You will unlock The Countermeasure. Get to the time machine via the elevator.
It's not the end - turn on the machine and kill incoming agents. Watch out for sharpshooters and two armored opponents. You can stay where you are, and wait for them to come after you. Activate the machine once again and get inside.
