Step by step guide for the Act 2 Finale

The finale of act 2 divides your squad into 2 teams, one airborne and one underwater. Everyone should stock up on snacks and armor prior to doing heists.

About the air team

The role of the air team is fairly simple - they only need to fly over the sub and take out the incoming hostile choppers. It is best to just fly high up so that the enemy choppers would have to rise to your altitude. Kill them when they are doing it.

Divide your team into 2

About the underwater team

The underwater team needs to get inside the submarine and keep killing until the end of the narrow passage. Enter the first set of doors you see, into a room full of screens and consoles. Kill the guards there and move forward until you see a set of stairs that lead down.

Narrow Passage
Shoot everything that moves

Follow it and turn left until you see a locker room. Pass through the locker room, kill the two guards in the kitchen then move to yet another set of stairs downward.

Door Right Sub
Get to the contact to speedrun Doomsday Heist

Turn right after going downstairs and go through a set of doors to get to the Russian prisoner, our contact target. Aim at the prisoner to get the information (do not shoot). Afterward, get back to the room with screens, take a picture of the table with your phone and plug the USB into one of the consoles. A cutscene would happen.

Swimming Shore
Assemble at shore then get back using the avenger

Once it ends, regroup with your friends on the beach. The quest will end once you land your Avenger inside Devin Weston's hangar.
