The Industrial Labyrinth is the fourth puzzle space in the Delver of the Cryptic event in Arknights: Endfield. Unlike earlier stages that focus on switches or rotating platforms, this challenge is built around navigation, memory, and pattern recognition.

At first glance, it looks like a simple maze. In reality, it constantly changes as you progress—opening false paths, revealing hidden chambers, and requiring you to remember specific clues. If you want to escape efficiently and collect all three hidden Labyrinth chests, this complete guide walks you through every section step by step.

Understanding the Industrial Labyrinth Mechanics

The Industrial Labyrinth revolves around:

• Corridors that reopen differently on repeat visits

• Hidden side paths triggered by revisiting routes

• Falling platform sequences

• Number-coded door logic

• Portal loops that reposition your character

Progress requires attention to detail and remembering specific sequences. Rushing blindly will only lead you back to earlier rooms.

Before diving deep into this puzzle-heavy event, make sure your Operators are properly prepared for surrounding content. If you’re progressing through multiple Delver stages quickly, Arknights Endfield Boosting can help you stay on schedule during limited-time events.

Step 1: Memorize the First Number

As you begin the Industrial Labyrinth:

• Move through the opening corridors.

• You’ll enter a room with a number written on the wall.

Memorize this number.
Write it down if needed—it becomes important later.

Continue forward as the maze funnels you through a single available path.

Step 2: The False Corridor Trick (First Chest Setup)

Eventually, you’ll reach a corridor that displays a chest at the end.

Here’s where the trick begins:

• Do not turn.

• Walk straight to the end of the corridor.

• A wall on the right will open.

This path loops you back toward the starting area.

What’s Happening?

The maze intentionally misleads you. The correct route only unlocks after you revisit the same corridor a second time.

Step 3: Return and Open the True Path

Repeat the same route to reach the corridor with the visible chest.

This time:

• Walk straight to the end again.

• The wall on the left will open instead.

Important rule:

The left wall reveals the real path—but only after completing the first loop.

This leads you directly to the first Labyrinth chest.

Step 4: Laser-Protected Chamber

After collecting the first chest, a protected room with floor lasers appears.

• Stay to the right side.

• Follow the narrow safe path along the wall.

• This leads to the next chamber.

No switch interaction is required—just careful movement.

Step 5: Falling Platform Sequences

Now you’ll encounter collapsing platforms. Stepping on the wrong one causes you to fall and reset.

First Platform Pattern:

1. Center

2. Center

3. Left

Second Platform Pattern:

1. Left

2. Center

3. Center

4. Right

5. Center

Follow these exact sequences to progress safely.

At the end of these platform puzzles, you’ll reach the second Labyrinth chest.

Step 6: The Numbered Door Maze (21323 Pattern)

After collecting the second chest, you’ll enter a room filled with numbered walls.

This is where the number from earlier becomes relevant.

Each numbered door leads to another chamber with more numbered choices.

To exit successfully, follow this exact order:

2 → 1 → 3 → 2 → 3

Entering doors in this sequence will unlock the correct route deeper into the maze.

If you make a mistake, you’ll loop back into previous chambers.

Step 7: Portal Corridor Puzzle (Final Chest)

The final section presents a long corridor filled with rooms containing portal devices.

At first, it looks confusing—but the solution is simpler than it appears.

How It Works:

• Enter any room containing an exit portal.

• Interact with it.

• You’ll be teleported into another similar room.

• Continue interacting with portals.

Eventually, one of these portal chains will lead you directly to the third and final Labyrinth chest.

There is no fixed visible indicator—the trick is persistence.

Step 8: Finding the Exit

After collecting the third chest:

• Return to the main corridor.

• Look for the room that does not contain a portal.

This room leads to the actual exit path.

If you get lost:

• Search for a corridor without a portal.

• Follow it straight without turning.

Eventually, the maze resolves into a linear hallway that leads you out of the Industrial Labyrinth.

Tips for Clearing Industrial Labyrinth Efficiently

1. Don’t Rush

This puzzle punishes impatience. Walk deliberately and observe wall changes.

2. Remember the “Revisit Rule”

Some paths only open after repeating a corridor.

3. Write Down Sequences

• Platform patterns

• 21323 door order

4. Prioritize Chest Collection Before Final Exit

Once you trigger the exit corridor, backtracking becomes more confusing.

Preparing for the Rest of Delver of the Cryptic

While Industrial Labyrinth is puzzle-focused, later event content may combine navigation with combat difficulty spikes.

If you’re aiming to unlock event story content faster or keep up with progression deadlines, Arknights Endfield Story Boost can help accelerate campaign advancement.

Is Industrial Labyrinth Hard?

Mechanically, it’s not difficult—but it’s mentally demanding.

The challenge comes from:

• Repeating paths

• Recognizing false openings

• Remembering sequences

• Avoiding maze loops

Players who pay attention will clear it smoothly. Players who rush may circle endlessly.

Final Thoughts

The Industrial Labyrinth in Arknights: Endfield is one of the most cleverly designed Delver of the Cryptic puzzles. It blends memory, logic, and environmental awareness into a maze that constantly evolves.

To recap:

• Memorize the first number.

• Repeat the chest corridor twice.

• Follow platform sequences precisely.

• Enter numbered doors in 2-1-3-2-3 order.

• Use portal rooms until reaching the third chest.

• Find the corridor without a portal to exit.

Master this stage, and you’ll be ready for even more complex Delver puzzles ahead.
