If you’ve ventured near the tunnels adjacent to the manor in Blue Prince, you may have noticed wooden crates obstructing your path. It’s clear that something significant lies hidden beyond them, but the challenge lies in figuring out how to remove those barriers. Luckily, there’s a solution that involves one of the game’s intricate mechanics: the Laboratory.
In this guide, we’ll explore how to access the concealed path behind the tunnel crates.
Clearing Tunnel Crates in Blue Prince
The method to eliminate the tunnel crates is rooted in Laboratory Experiments. These experiments utilize specific terminals located in various rooms, enabling you to trigger different effects during your gameplay sessions.

To initiate the process, follow these critical steps:
- Complete the Laboratory Puzzle: Successfully solving this puzzle will grant you a permanent perk, enabling remote access to terminals from specific rooms, such as the Security Room.
- Collect All Three Microchips: Once inserted into the Sundial, these microchips will unlock a data packet, broadening your experimental capabilities.
- Utilize a Terminal: With the previous tasks completed, log into any terminal, enter your passcode, and select “Data Transfers” to initiate an experiment that clears crates.
These achievements represent lasting milestones in your progression, enhancing your experience in every subsequent run.
Once you’ve gained access, you need to select the right experiment combination. Look for effects that state something akin to “removes a crate from the tunnel whenever X occurs.”
Next, choose a cause that can be easily triggered multiple times within a single gameplay session. Here are some effective combinations to consider:
- Unlocking Security Doors: This approach is efficient and yields multiple results. In the Security Room, adjust the system to high security while toggling offline mode to “unlocked.”This action can create up to eight additional doors throughout the manor. If you possess a Keycard or have deactivated the VAC Control from the Utility Closet, simply navigate through these doors—each one you unlock reduces the number of crates in your way.
- Digging Up Trash: If you have access to the Root Cellar in your room, you’re in luck. This area is rich in dig spots. Equip a shovel and start excavating. Each time you unearth something, often deemed useless, you’re simultaneously aiding in crate removal. Additional dig spots can be found scattered throughout the manor, so feel free to explore other locations too.
- Consulting Your Map (While Losing Steps): This trigger, though a bit unconventional, proves to be surprisingly effective. By opening your map, you risk losing 10 steps but simultaneously eliminate a crate. It’s a calculated trade-off. If you’ve previously explored locations like the Sauna or received the Apple Orchard buff, you’ll have bonus steps, allowing more frequent map checks and expediting the crate-clearing process. Although your runs may finish quicker, the progress made is invaluable.
It’s important to note that clearing all the crates in one attempt isn’t feasible; there are numerous crates, and it will require several runs to overcome this challenge. However, by consistently utilizing effective experiment combinations and prioritizing crate removal during your gameplay, you can achieve your goal quicker than anticipated.
