HR: Human Remains secrets & hidden places
The usable phone is on a balcony in archive section H: position a cart, reach the third-floor opening and jump through. For the cat, follow the reported construction platforms to the roof. Some old secret phone numbers were cancelled.
The most useful detours are the portable phone in the Archives, the construction-site rooftop and the server-room box. These routes contain location spoilers. For the full six-item hunt, use the figurine checklist.
Find the usable phone in archive section H
Developer dennisCorner's October 15 directions identify section H, a balcony and a movable cart.
- Look for the balcony in that archive section.
- Push a cart into position to gain height.
- Use the opening on the third floor to jump through to the balcony.
- Collect the phone there and use it later in the shelter.
This is the portable phone for Connected!. A telephone elsewhere with buttons does not necessarily serve the same task. If you have numbers but cannot make a call, first check that you collected this handset.
Why an old secret number returns invalid
In the same thread on October 15, the developer says the secret numbers no longer work and were cancelled. Do not keep repeating an old code simply because it appears in a launch-week achievement post. Find a number from the relevant character or shop in your game, and keep the handset problem separate from a number problem.
The doctor number in the thread also receives a player correction. Copying a stale list therefore creates two different failure risks: an obsolete secret and a transcription error. Read the current in-game number rather than substituting one from an old quotation.
The cat's construction-site roof
A separate October 4–5 community discussion describes this route after entering the construction area:
dirt pile → shipping container → first floor of the construction building → excavator → two arches → sanitation truck → roof.
The more detailed route was posted after another player's shorter dirt-pile-to-vehicle suggestion was disputed. Line up the intermediate platforms instead of assuming a direct jump from any truck works. Access to the construction site and climbing to the cat are separate stages.
Later achievement-thread replies report both hacking-tool and demonic-upgrade ways into the area. Use the route suited to your current character; choosing Eye is not established as the sole prerequisite. The portable-toilet figurine is another stop in this area, below the rooftop task.
The box after Chihu
After freeing Chihu in the server room, watch for a box falling open and collect the figurine inside. This location comes directly from the developer's October 1 reply. It is part of Collector, while freeing Chihu itself is the Liberation task described by the community route.
A detail that is not a hidden puzzle
The scientist-room plant prompted an achievement-thread question on October 13. The developer says it is a small detail, not a puzzle. Leave it and follow the current task if you are searching for a missing progression trigger.
Plan the detours around your task
Take the archive phone while you are in section H, inspect the Q/R room for its figurine, and check the construction toilets while working around the cat's location. These are different objects with different purposes. The walkthrough groups the route stops, and the puzzle page covers actual LiDAR and bait blockers.
