Deathloop is not as obtuse as the concept would have one believe, but there are still some puzzles with the ability to stump players. Particularly, there is one mysterious door in Updaam that is locked behind a password.

Once Colt gets this door open, he discovers there are three more Deathloop codes he needs to find. Players cannot simply ignore this one because it is a vital part of the story and breaking the loop. If anyone is having trouble with this part of Deathloop, just read the guide below and Colt will have the door open in no time.

Starting Radio Silence

Players find the start of this quest in Updaam. Head to the northwest corner of the map (near the tunnels) to find one of two clues. The locked door is down a flight of stairs, and nearby there is a note pinned to a garage. If Colt is there at the wrong time of day, the clue will tell him to come back in the afternoon once the garage is open in the afternoon.

When the garage door is open, head inside and go to the top floor. Enter the room and go to the left. A note is sticking out of a bookshelf that reveals the password to the RAK door. Head back to the door outside and open it, which then leads to another locked door. There is a note here that reveals a password players use in the Power Station in The Complex.

The Power Station

Julianna does not want Colt entering the power station, which means this is exactly where players need to go. Once inside, There are four generators in two adjacent rooms Colt has to power up with a battery.

Find one of several empty batteries around the area and recharge it using the charging station located in between the two rooms. Go up to the generator, insert the battery and press the red button underneath the battery slot.

Colt only needs one battery to power up all the generators. Once they are all on, go back to the control room at the top and players can now open up the 4 HZN Doors located throughout Blackreef.

HZN Door Locations

deathloop HZN door locations

There are four HZN doors located throughout the area which contain three passwords. The first one is extremely easy to find since it is right next to the power station and Colt points it out. Keep in mind that only two doors can be powered up at once, so players will have to return to the Power Station at least once to divert the power to the necessary doors. The other three doors are in the following locations:

HZN door updaam
  • Updaam: The door is located to the right of the bridge where Charlie set up his game. The bridge is up at all other times of the day except noon, but the HZN door can be opened at any time of day. The passcode is located in a document on a table at the top of the stairs called Classified Information.
Deathloop Karl's bay HZN door
  • Karl's Bay: Colt finds this door in a corner of the map. Head to the hangar where Harriet is found in the morning and then head to the corner of the map opposite of it. If players are oriented right from the start of the map after leaving the tunnel, it is on the far left corner of the map. Depending on the time of day, there will be a sniper and a bunch of landmines. Once inside, a small cutscene plays and the clue to the password will be in an audio log on the floor.
deathloop HZN door fristad rock
  • Fristad Rock: This one is perhaps the most challenging to find. Go to the comms base (a ruined grey structure). For reference, this is the same comms base where the antenna shows up when Julianna invades the player's game. Run past this structure and drop down the rocks below. There is a bunker entrance here where players enter to find Fia. To the left of this area is the HZN door. The passcode is on a table at the far end of the room, opposite the exit door (which leads into the room with the nuclear reactor core).

After finding each password, head back to Updaam, and a cutscene will play. This room comes into play during the final loop when Colt tries to escape Blackreef.
