In the Lies of P: Overture DLC, players can find and solve three secret Cipher Machines around the game world. Each Cipher Machine points to a special puzzle, where you must kill tough enemies, find hidden objects, and make decisions in order to receive special rewards. Doing all three not only rewards you with precious equipment but also unlocks an achievement. In this guide, we will explain where and how to find each Cipher Machine step by step.
All Cipher Machine Locations and Solutions
To unlock the Tracker of Dark Secrets achievement, you need to find all three ciphers and solve the cipher machine puzzles. Remember, when you are given a dialogue choice, make sure to select “They will be, and Krat will be saved.” This choice unlocks an extra reward and helps you work toward an additional achievement.
First Cipher Machine (Bloody Cipher Machine)


First, you need to defeat the Two-Faced Overseer boss to get the Bloody Cipher Machine. Once you beat him, the machine will automatically drop. After that, go back to the Eventide Hotel and talk to the Tracker NPC. Select the option to “Decrypt a cipher machine.” After decoding, you will see a picture of a stuffed crocodile.

Now, head to the Hall of Adventure. Go straight up the stairs, turn left, and enter the first door you see. Inside, you will find the stuffed crocodile from the picture. Interact with it, and its mouth will open to reveal a necropsy report. Pick it up and bring it back to the Tracker to complete this cipher. As a reward, you will get a whirlwind amulet.
Second Cipher Machine (Corroded Cipher Machine)
For the second machine, make your way to the Ergo Mining Site. There, you will encounter an elite enemy named Bullzdozer. Defeat him, and you will get the Corroded Cipher Machine. Like before, return to the Tracker at the hotel and have it decoded.

Once decoded, head to the Ancient Ruins Excavation Site using fast travel. Look for a rock wall you can interact with. Use an explosive to break through, which will reveal a small cave. Inside, you will find the Misfit’s Diary. Take this diary back to the Tracker, and you will receive an ancient disk as your reward.
Third Cipher Machine (Frosted Cipher Machine)
To find the third cipher machine, go to the Archon Fleet Ship and locate the shipwrecks. You will find a safe guarded by an elite enemy. Defeat the enemy, open the safe, and collect the Frosted Cipher Machine.
Bring the machine back to the Tracker for decoding. You need to kill the leader of the Bastard Story Boss to decrypt it. After it’s decoded, teleport back to the Archon Fleet Shipwrecks and find the Wandering Merchant near the stargazer. Buy the Giant’s Amulet from him; it will make your weight “very heavy” when equipped.


Now, teleport to Krat Lighthouse. Equip the amulet and step on the weight-sensitive floor panel. Your heavy weight will activate the panel and open a secret room. Inside, you will find the Lighthouse Keeper’s Journal lying next to a body. Pick it up and take it back to the Tracker. Your reward this time will be a set of detective’s clothes.
