How to do Sewer Branch puzzle in Rust

On the long list of Monuments present in Rust, we have covered what you can do and find in the Launch Site, Power Plant, Water Treatment, Military Tunnels, Train Yard and Airfield.

We have a brand-new Monument for you this time, and you might need to take a bath afterward.

That’s right, this time we’re getting deep into the Sewer Branch to discover its secrets and loot.

Of all of the lower-tier Rust Monuments, the Sewer Branch is one of the most interesting in terms of design, and it has one of the most interesting puzzles as well.

There’s a lot to talk about, so let’s Get Down in the Sewer Branch.

The first thing you should know about the Sewer Branch is that it doesn’t consist of tall buildings that you can see from far away.

The entire Monument is recessed into the ground, so you might have some trouble finding it initially, or you could stumble into it, potentially to your death if you aren’t paying attention.

It can be located on the player map, but it’s a good idea to watch your step in general in this game.

In terms of danger, the Sewer Branch isn’t guarded like the Military Tunnels or Launch Site, so you won’t run into any Scientists as you explore.

There is, however, a low level of radiation that is emitted by the location.

You won’t need a full Hazmat Suit, but it would be a good idea to have at least a full Burlap set.

This makes the Sewer Branch pretty accessible even to new players as well.

Due to the high accessibility of this Monument, you will most likely encounter other players here, so make sure you have weapons and ammo in case things come down to violence.

There are plenty of places to hide and plan ambushes that you can make great use of.

That also means that other players can use them too, so be wary of corners and low-visibility areas.

As previously mentioned, the design of the Sewer Branch is exceptionally interesting.

The entire monument consists of a tall metal tower recessed in the ground, several metal shacks that dot the cliffs surrounding the chasm, and also a cave system that runs underneath the whole thing.

You can find all kinds of loot in each location of the monument, including Regular Crates, Food Crates,  and Medical Crates.

There are crates that can be found on top of the metal tower, but reaching that area will require you to do some careful platforming.

The area is high enough that slipping and falling off can result in the loss of a chunk of health, or even death, so get those platforming skills sharp!

How to solve Sewer Branch puzzle?

Now, for the really interesting part of the Sewer Branch.

In order to solve this puzzle, you’re going to need a Green Key Card and a Fuse.

You’ll begin this puzzle by locating the Red Metal Shack along the cliff of the area.

Inside, there will be a fuse box where you can install your Fuse.

After you have installed the Fuse, make sure you flip the switch next to it to turn on the power.

Then, leave the shack and follow the high power line that travels outward from it.

It will go down through a tunnel entrance into the lower areas, so use the ladder and follow it.

At the bottom of this ladder, there will be two possible paths you can follow.

Don’t think about it too hard, as they both take you to the same room, just down different ways.

It’s going to be dark, but there is a light at the end of the tunnel so you won’t really need a torch.

At the end of the tunnel will be the Green Door, where you will swipe your Green Key Card.

Then enter into a large room, where you will actually need a torch to see everything clearly. Taking a right after you enter, you’ll be able to find a combination of Basic and Military Crates.

Don’t worry, this isn’t the big reward for the Sewer Branch puzzle, just some fun extras.

Once you have collected those crates, continue going right through that first room until you find an open sewer entrance.

Once you go through that threshold, you will be in the real puzzle reward area.

You’ll be able to find several more crates of all different kinds here.

Also, make sure you check the desk for your Blue Key Card, you’ll need it for High-Tier Monuments like some of the ones we covered previously.

There are several tunnels leading in and out of the area, through which you can find the secondary door to the puzzle room.

This door is only powered as long as your Fuse lasts, so keep an eye on that if you’re going in and out.

And that’s the end of the Sewer Branch Monument.

It’s far less complex than the other Monuments we have covered, but it is a Low-Tier Monument, so it’s to be expected.

In addition to encountering other players here, you likely won’t find fresh spawns of loot as it will be a high-traffic area with other players collecting things before you get there.

However, there is plenty to explore, so you can occupy yourself while you wait for those crates to respawn.

If you want to use the Sewer Branch as a sort of base, there are a few recyclers that can be found above ground close to the shacks, and also an oil refinery in the final puzzle room.

These are great if you need to break down some resources or craft some Low-Grade Fuel for use at the Train Yard.

As long as you’re prepared and watching your back, there is plenty of utility to be found in the Sewer Branch as well as the area surrounding it.
