Archives Gate
🔷 Optional
📑 Sparky Please

Dorsey Square Tunnel
🔷 Optional
📑 Scribbled Notes

Underneath Dorsey Manor, on the outskirts of rocks near Otto's Workshop you can drop down into the ditch to find a cave entrance. The cave leads to a map with locations marked, 3 triangle diagrams & a locked safe. I recommend attempting this during Noon where you can access the entire map.

Code Order: The 3 triangles correspond to 3 codes that must be entered into the safe, from top to bottom. The first triangle is already placed correctly on the map, so you only need to figure out where the other 2 triangles go by matching the skull & ring symbols with the corresponding points on the map.

The codes must be entered from first to last, you have unlimited attempts, and the safe will indicate to you when you have gotten each part of the code correct.

Number Order: The order you must input the numbers in each code are indicated by the slashes on each corner of the triangle. No slashes will be the first number of the code, 1 slash is the second number, and 2 slashes is the third number. Keep in mind the third triangle is faded out, so you are forced to guess the order of the numbers for the third code.

Number Locations: The actual numbers you will need to use are written around the map, so you will have to find & record them. They are written in black ink & surrounded by a circle. Once you have noted down all 6 numbers & their locations you should have everything you need to solve the code.

Reward: The safe contains 5,000 Residuum, which can be collected every time you loop.

To get started we will want to head to Fristad Rock - Morning. Along the shore right by Colt's Tunnels we can find a Hideout, and conveniently this bunker has a hidden entrance a bit further along on the side of the rock cliff. Once we gain access to this first bunker we can read all the notes & listen to the Cassette to get the information we need.

The note on the table here will also have the first code.

To find the locations of the Hideouts & how to gain access to them you will first need to tune into the mysterious radio broadcast that plays only in the morning across Blackreef. There is a radio already in the Fristad Rock Hideout that we can use to tune into this message.

The message will contain a series of letters & numbers which indicate the Map Coordinate of the Hideout & also the number of times you must ring the doorbell to gain access to each location.

M13 // Number
H26 // Number
R33 // Number

Using the Maps we find around Blackreef we can pinpoint the exact locations of each Shelter. You can check these Coordinates yourself at a map when you arrive in each area, there is usually one found near the Tunnel Entrance, but I have listed below their locations:

R33 // Fristad Rock // Spy HQ
M13 // Karl's Bay // Near Treasure of the Ice
H26 // Updaam // Near Otto's Workshop

To check if you are understanding the radio message properly you can test it already at Fristad Rock. If you leave back through the tunnel, return to the main door entrance & smash the wooden boards blocking the door you can ring the doorbell the correct number of times & the door should unlock, be sure to press the button quickly without any large gaps between presses.

Updaam Hideout is located near Otto's Workshop, it is in the building just to the left with a blue door (Coordinate H26). Ring the doorbell the correct number of times indicated in your radio transmission to gain access & then be sure to read all notes in the Hideout to acquire the second code. You will need to smash the glass panel blocking the door way to access most things of importance in the room.

Karl's Bay Hideout is located near Treasure of The Ice along the Main Road (Coordinate M13). Ring the doorbell the correct number of times indicated in your radio transmission to gain access & then be sure to read all notes in the Hideout to acquire the third code.

With all 3 codes you are ready to return to Fristad Rock & open the Archives door. You can input the 3 codes in any order & the door will unlock.

Reward: 🟪 Tribunal [Shoot to Tag] & 🟪 Tribunal [Extra Damage When Tagged]
