Deathloop guide – How to unlock the HZN Mysterious Door in Updaam (Radio Silence quest)

Updaam (afternoon)

The Mysterious Door in Updaam, the one with the HZN writing, is actually part of the Radio Silence quest. Ideally, you should first have access to the Power Station in The Complex. There’s an HZN facility there that gives you an important document. It talks about the Horizon Archival Office in Updaam.

Go to Updaam in the afternoon and, from the entrance tunnels, make your way up the slope. Follow the cliffside path to reach the Mysterious Door. The Horizon Archival Office, meanwhile, is fairly close (it’s at the grassy area). The shutter is only open during the afternoon.

Inside, you’ll find out that this is actually Julianna’s home in Blackreef. There are lots of documents here, the most integral one tells you about the passcode for the Mysterious Door.

In my case, the passcode I code is “Tambour.” I’m not sure if this is randomized for other players.

Anyway, press the button on the Mysterious Door and Colt will speak the password. It will open up, and you can check out some of the stuff here. You’ll notice a rocket ship known as the Rakyetoplan (RAK for short). If you check the door to the RAK hangar, you’ll see a note with a numerical code. Again, it might be randomized for other players (mine is 5-2-4).

The Horizon group also locked the hangar. To open it, we need to speak three different passcodes. We’ll obtain these from the other HZN facilities in Blackreef.
