What’s Behind the Secret Door in Serif Station: Destiny 2 Guide

Share This Post


Serif Station in Destiny 2 holds a handful of secrets. Some of them are obvious like the 12 hidden security drones scattered around the place that each require a season unlock to get to. And then there’s the more subtle ones, like the maintenance drones that you need to destroy to unlock the secret chest at the end of the level.

But regardless of your level of knowledge of the station’s secrets, there’s one question that many patrons ask, “What’s behind the secret door of Seraph Station?”

In this guide, we’ll tell you how to open the door and what’s beyond. Spoiler alert. It includes some puzzle platforming.

Where to find the secret door at Serif Station?

The secret door is located in the atrium past the loading bay of the station. But in order to have a chance to interact with the door, you’ll first need to unleash Haruktha, the curse of the helium drinkers. This mini-boss fight shouldn’t take long since this is the second time the two sides are fighting each other.

How to open the secret door at the serf station.

To open the secret door, you will first need to destroy the 50 drones scattered throughout the system. They can be found in open world areas, Seraph missions, and within the Seraph Station itself. We have a separate article that tells you where you can find all-terrain drones. (You’ll also need the Revision Zero Plus Rifle to destroy them.)

The lights to the left of the door indicate which ones you still need to get and light up whenever you destroy one. When all the drones are destroyed, you can open the door.

What’s behind the secret door at Serf Station?

Upon opening the door, you’ll be greeted by 3 sets of laser traps. To get past them, you’ll need to upgrade the Exo which reduces the damage you take after tripping the laser.

Next, you’ll find a security door. Interact with him and you’ll be tasked with shooting three sigils at the walls. The first two are fairly easy to find. The last one, however, is located on the wall in the back hallway.

After opening the door, you’ll take a teleporter to the station’s maintenance structure. This is where the puzzle-platforming section begins.

Follow the catwalk and pipe path towards the bright light. The trail is occasionally marked by glowing dog paws but they are few and far between. Continue in this general direction, looking for the red lights that indicate the landing platform. Your first obstacle is a pipe. Check it out, and you’ll find the next platform. It’s a bit steep but you can easily get there safely.

The next section introduces constellations. While these aren’t too much of a threat, you’ll still need to be a bit careful, especially on Legend difficulty.

Go to where you destroyed the turret, and from there you’ll be given two options: go straight to the door or go straight to another platform.

Go right and jump the platform. (That room looked suspicious anyway.)

Be careful about jumping on the big pipe. A turret is waiting to shoot you when you enter line of sight.

The next part is pretty much the same as you’ve been so far, but you’ll be jumping on platforms connected by diagonal pipes. The cave area leaves quite an impression.

Fight your way through until you reach the door at the end of the chasm. It’s a short distance, so watch your height when trying to jump. Inside the room on the other side are a couple of turrets.

Once you’ve tackled both turrets, you’ll be asked to choose a path down. Please choose the white lighted lane. (Three guesses as to where the red light goes.)

At the end of the room you run into is a section of pipes that you have to slide down to proceed. The thing is, it’s a leap of luck. sort of. Chances are you won’t see the landing platform until you’re near the end of the slide. One jump is all it takes to cross it safely before being dropped.

After falling down a little further, you’ll be asked to choose where to fall. Your options are the slide under the red light or the other two under the white light. Select the slide under the white light.

Before exiting this area, there will be two turrets covering the door.

The final part of the puzzle requires you to jump down to a door quite a distance away. From the image above, you can barely see a white square on the bottom left of our reticle. This is where you need to go down. It’s almost a straight drop, but we recommend jumping halfway and falling a bit before deciding to double jump.

Alternatively, you can target the pipes above the door. But knowing how things stack up on such thin platforms doesn’t fill us with much confidence.

So what’s at the end of this little adventure? Why is this a Cute robot dog. Of course.

Interacting with the robotic K-9 allows you to activate the Good Boy Protocol.

What is Good Boy Protocol in Destiny 2?

Good Boy Protocol plays an animation in which your Guardian pet the mechanical dog and the dog reacts to it. This is actually a neat little secret.

On a side note, you also need to do all of this for your Seraph Cell to conquer Guardian’s Best Friend. It’s all about destroying the drones as well as whatever secrets this season has to offer.

After petting the dog, what you need to do next is take the teleporter back and you’ll be in front of the secret door again. You end the level from this point.

So, what happens after you encounter a robot dog?

Congratulations, you and the HELM crew are now the proud owners of a modern mechanic dog. The adorable dog can be found in front of the Exo frame. And we can’t help but cherish it when we’re there.

And yes, it’s a win for Maher too.

That’s it for this guide to what’s behind the secret door of Seraph Station. It has been a wild ride meeting all the demands and being patient all the time. It’s been a secret and we’re really glad Bungie added it to the game.
