Don’t know how to start and complete the McMillan Reservoir Assault Classified Assignment in The Division 2? The locations of all the ECHOs and audio logs, solutions to puzzles, the new Backpack trophy, and such- I’ve got you covered with my walkthrough guide.
After the Library of Congress Retrieval and The Capitol Anomaly classified assignments, the most recent one, McMillan Reservoir Assault, is finally here.
Just like any other Classified Assignment, completing it rewards players with a High-End weapon, the Old Glory Sub Machine Gun in this case, and a unique Backpack Trophy called The Big Foot, along with Echoes for Lore Hunters.
That said, there are sections and puzzles that many players may get stuck at while clearing McMillan Reservoir Assault Classified Assignment.
For them, my walkthrough guide will be handy!

Go to the right side of the platform, drop down, and head to the lever found on the right.

You will finally find yourself within the reservoir. The water in the area is electrified.
In this area, there are two things that you must do:
- Find two Generators and disable them to get rid of the electricity
- Collect the first Audio Log
Climb up the cars and follow the path leading towards the silos.
Go through the Silo to reach the other side. Once there, look on your left. You will find the first generator.
Go through the silo door and look on your left. You will find concrete blocks that you can climb to reach the generator.

Go through the door, and within the Silo, you will find the first log.
Collect This Is Our Castle Now Audio Log.
Now head back to the silos area.
At the above location, you will find the Silo that holds the Bigfoot Backpack Trophy and the final Audio Log, along with a True Sons Cache.
To access it, you must solve a Water Valve puzzle that I will explain later.
Back to the quest, don’t head towards the turrets.
Instead, wait for the dialogue options to complete and then move to the door that you see in the above screenshot.
Go through the door and follow the path.
Inside the shed, you will find a locked white door leading to a Blue Water Pump. It is one of the three that you need to access to unlock the Silo holding the Backpack Trophy and other items.
For now, follow the main path.

In this section, you must destroy two Radio Equipment.
But first, follow the path on the right side to reach the above location. Interact with the panel. You need it to unlock the cover protecting the circuitry.

Head back to the top and use the Laptop.
Shoot down the two circuits.
Go through the gates.
Defeat the enemies in the area.
Take the stairs.

Now, take the stairs to reach the first floor of the Pump House.
There you will find Water Pressure Indicators for three Pumps.
They are labeled 1, 2, and 3. Note down the pressure on each of them.
Note: In each run, the pressure will be different.
On your left, at the player icon location, you will find the first water pump.
Set the pressure corresponding to Valve 1.
Now, head to the other side of the room, to the player icon above; you will find the second valve.

As you exit the Pump House, on the right side at the player icon location above, you will find Pressure Meters for three water pumps.
Unlike the previous one, there’s no number. Instead, each has a unique color. Green, Blue, and Yellow.
You need this to solve yet another water valve puzzle to obtain the key leading to the Silo with the Backpack Trophy.
For now, note down the pressure readings and their respective colors.
Follow the quest marker. Place the explosives.
Go through the broken wall to reach the underground area of the Pump House.
In this section, your goal is to find and open four water valves to unflood the area and then destroy four pipelines.

Head back towards the radio tower.
You will find the Yellow Water Valve there.
The issue is, you need a Fuse to set the pressure.
Take the stairs.
Go to the radio tower.
Follow the above path. You will arrive at the door I mentioned earlier in this guide. Now, it will be open.
