Act V - Final Moments | Walkthrough Quantum Break Guide

Another Chronon Source is by the wall, outside the building

Exit the cab, turn right and head to the corner to find a Chronon Source. Follow Will to the building. When you get upstairs, you will come across a radio that will play a different recording this time.

Locate another Source

Help your brother to smash the door and go through the locker room. Turn right twice and locate another Chronon Source next to the shower. Enter the time machine. A small group of enemies is already waiting for you in the future.

Final opponents are in no way extraordinary

Unfortunately, when you try to wake Will up, Paul will appear and your final fight will begin. The rules are simple - survive three waves of enemies, supported by Paul's grenade attacks.

The red wave is deadly but you are safe until it actually explodes

After the first wave, Serene will perform a special attack and red waves will be emitted from the source. If you end up in that zone, you will die. The only way is to run to the other side of the pool to save yourself. When you are safe, shoot at him (he is standing above the time machine).

The same procedure will occur after the second and third wave, but this time Paul will perform three of his special attacks. Shoot him and finish the final battle.

All you have left is to help Will with the time machine and complete the last chapter of the game. You will unlock another achievement, Your Exceptional Qualities Are Obvious. Apart from that, you will unlock an achievement that depends on the difficulty level (the one you used during your gameplay).
