The Conspiracy Mystery Walkthrough

"The Conspiracy" iconThe Conspiracy is one of the most complicated of the mysteries available in Hell is Us. Players will start this early on in Lake Cynon when they collect a note alongside another document. However, you will be able to progress this without world touring for clues in various levels through Act 2. That’s unless you don’t use a guide or ask for help solving it. Here’s how to solve the Conspiracy mystery in Hell is Us.

The Conspiracy Walkthrough

The Conspiracy Mystery can be solved regardless if you have the clues or not. To do so, you need to do the following:

  • Complete Act 1 and unlock new areas for Act 2.
  • Go to Acasa Marshes and complete the Pathom Abbey missions.
  • Work your way through the Abbey and learn of a book. This unlocks the Lethe - National Library map.
  • Go to the Lethe National Library, and make your way up the stairs from the Delivery area.
  • Follow the corridors around the upstairs and enter Computer Room D, the room mentioned in the first note you found in Lake Cynon.
  • Open the terminal and enter the code: 731956

Input this code to get access to the conspirator’s documents and learn more about the partial truth, partial unhinged events. Image via Gamer Guides / Nacon.

You will now be able to access the notes on the conspirators and what they know. There’s three files relating to infiltration, the conspiracy itself and the What Lies Below section. The idea talks about powerful leyline energies, a popular idea in conspiracy theory energy sources for the strange. It’s a nice blend to explain what the Lymbic Entities are and how the OMSIF know what they are and what they are doing within the game. There’s no traditional reward in that sense unless you’re into the lore.

If you want to do this the old fashioned way, you need to find the note clues across all major maps:

Location Details Requirement
Lake Cynon At the end of the road from the APC N/A
Telju Inside the bus stop next to the Pharmacy Requires Act 2
Marastan Inside the market next to the church on top of the hill that you can see from the APC. Complete Telju first before unlocking this area.
Jova Garage Go to the gas station on the south side of town and check the back of the garage. N/A
Lethe - Ministry for Culture Besides one of the large reception desks. Start Act 2
Lethe - National Library By the corridor on a table that is near an ‘employees only’ sign Complete Pathom Abbey in Act 2 first to unlock.

That about concludes all you need to know about the Conspiracy mystery in Hell is Us. Good luck tracking through the rest of the mysteries and good deeds that players can complete for their 100% achievement. If you want tips on some of the other harder to solve ones, we recommend you do Enlightenment next.
