Before You Start
Is The Prisoner a separate chapter?
The Prisoner is the first chapter of REANIMAL's The Expanded World post-launch DLC campaign. THQ Nordic announced three DLC chapters as part of the campaign, with The Prisoner being the first.
That distinction matters because this guide covers The Prisoner specifically, rather than the nine-chapter main REANIMAL campaign.
The DLC also has its own set of 10 achievements/trophies worth 315 Gamerscore on Xbox.
Can you play The Prisoner solo?
Yes. REANIMAL supports single-player as well as local and online co-op, so the guide's companion interactions can also be performed with the AI partner when playing alone.
DLC Progression Overview
The Prisoner is fairly linear, but several areas contain optional side routes.
The major progression sections are:
- Opening wilderness/canal route
- Shopping mall
- Hidden arcade
- Flamethrower encounter
- Scorched Earth
- Metro station
- Metro train puzzle
- Keycard/security area
- White Rabbit backtrack
- Metro ticketing hall
- Outdoor street
- Final bridge
The biggest route warning comes near the end of the Metro section:
Do not forget the Keycard backtrack.
You need to obtain the Keycard first and then return through the previous squeeze route to reach the locked subway-track door containing the White Rabbit.
Opening Area and Super Fly Poster #1
Begin by following the main route through the flooded area.
Before squeezing through the wooden fence gap, check the small wooden footbridge.
Super Fly Poster #1
The first poster is attached to the left post of the small wooden bridge immediately before the squeeze-gap.
Interact with it to register the first poster.
Quick check
Poster #1: Wooden bridge → left post → before the fence squeeze-gap.
This is an easy collectible to miss because the main route naturally draws you toward the squeeze point.
Reaching the Mall
Continue toward the shopping mall.
Before entering the obvious route, look underneath the wooden deck.
Super Fly Poster #2
Go underneath the wooden deck and follow the crawlspace toward the canal edge.
Turn left rather than immediately continuing toward the mall entrance.
You'll find the second poster along the wall.
Poster #2: Under-deck crawlspace → turn left → canal-side wall.
Mall Secrets, Poster #2 and Poster #3
Once inside the mall, don't immediately follow the main path.
The apparel store contains an important hidden route.
Super Fly Poster #3
Enter the first apparel/clothing store and look for the fallen posters and clothing rack.
Crouch through the right-side clothing rack.
This leads to a wall opening and a hidden room containing Poster #3.
Remember this route
Clothing rack → wall hole → hidden room → Poster #3
This is one of the DLC's more easily missed environmental collectibles because the entrance blends into the store clutter.
Smile for the Camera
While exploring the mall, look for the soldier photo stand-in.
One character needs to position themselves behind the cutout while the other takes the photograph.
In solo play, the companion can be commanded into position.
Achievement: Smile for the Camera
To unlock it:
- Find the soldier cutout.
- Position the companion behind it.
- Use the companion command if necessary.
- Stand in front of the cutout.
- Aim the camera.
- Take the photograph.
The achievement is tied to photographing The Soldier at the photo stand-in.
Arcade Secret and Space Suit / Astronaut Helmet Mask
The mall also contains a hidden arcade.
Look for the fountain/tank mechanism.
How to reach the arcade
- Activate the relevant sprinkler/fountain mechanism.
- Rotate the fountain tank fully to the left.
- Use the resulting route to reach the upper ledge.
- Open the hidden route into the arcade.
The arcade contains another secret interaction and the Space Suit / Astronaut Helmet Mask cosmetic.
Stalking Shadow
Check the back wall behind the arcade machines.
Use the camera flash when you spot the suspicious shadow.
This contributes toward Frame Fatale.
Flamethrower Encounter and Poster #4
Continue through the mall until the flamethrower encounter.
After surviving the encounter, don't immediately leave the room.
There is an important hidden route.
Poster #4
Look for the wooden bookshelf on the left side.
You can use an unexploded grenade from the area to destroy it.
Route
Pick up grenade → throw at bookshelf → bookshelf destroyed → squeeze through opening → Poster #4
This is one of the most important hidden routes in the DLC.
If you're collecting all six posters, don't skip this room.
Blood Hound Suitcase and Exploding Suitcase
The Prisoner has two visually similar suitcase types, but they serve completely different purposes.
| Type | Purpose |
|---|---|
| Blood Hound suitcase | Open it and photograph the red symbol |
| Exploding suitcase | Open it to trigger a fatal explosion |
The DLC achievement list confirms that The Blood Hound requires finding and activating the opened suitcases, while Definition of Insanity requires being killed by all exploding suitcase traps.
Blood Hound suitcase mechanic
Opening the suitcase is only the first step.
You must:
- Open the suitcase.
- Equip the camera.
- Aim at the inside of the case.
- Trigger the flash.
- Wait for the red symbol to illuminate.
If you simply open the case and walk away, it won't register the same way.
Important visual clue
The safe collectible cases reveal a red sigil/symbol when photographed.
That is your confirmation that the interaction has been completed.
Warm Bodies
After the flamethrower encounter, look for the fireplace room.
You'll find two armchairs positioned beside the fire.
Achievement: Warm Bodies
Have both playable characters sit in the chairs.
Don't immediately move.
Wait for the camera to complete its wider framing/pan.
The achievement is tied to resting beside the fire.
Quick tip
If nothing happens immediately, stay seated.
The camera movement is part of the trigger.
Hidden Stairwell and Stalking Shadow
The fireplace area also contains another hidden route.
Look for the bookshelf mechanism that opens the secret passage.
Follow the dark staircase down.
At the bottom, surrounded by piles of books and paper, you'll find another Stalking Shadow.
Use the camera flash to expose it.
Frame Fatale tip
The Stalking Shadows don't behave like normal collectibles.
There isn't necessarily a standard interaction prompt.
Instead:
Aim camera → point at shadow → flash → shadow disappears
This counts toward Frame Fatale, which requires photographing all stalking shadows.
Scorched Earth and Remains of the Day
Continue into the bomb-crater area.
Before dropping into the main crater route, explore the right-hand edge.
Stalking Shadow
Check the wrecked civilian vehicle near the crashed transit bus.
A shadow is positioned on the vehicle.
Use the camera flash to clear it.
Remains of the Day
Continue along the narrow dirt rim of the bomb crater.
Do not drop into the crater immediately.
Follow the ledge until you reach the solitary chair.
Sit down and wait for the camera to pull back.
This unlocks Remains of the Day, which requires sitting at the edge of the bomb crater.
Easy mistake
If you drop into the crater first, you'll pass the chair without seeing it.
Metro Station and Exploding Suitcase #2
Continue toward the Metro.
Before advancing, search the platform for optional interactions.
You'll find another Blood Hound suitcase near the blocked escalator area.
Remember:
Open → camera → flash the red symbol.
Exploding Suitcase #2
There is also another booby-trapped suitcase.
Opening it causes an immediate explosion and death.
That's intentional.
If you're completing Definition of Insanity, you need to trigger both exploding suitcase traps.
The second trap completes the achievement requirement.
Don't confuse the two
The safe cases are collectible interactions.
The exploding cases are achievement traps.
They should not be counted together as one collectible category.
Train Puzzle and Petrified Spider Kids
Eventually you'll obtain the Axe.
This unlocks a new interaction type.
Petrified Spider Kids
The petrified Spider Kids can be destroyed with the Axe.
You can either:
- Swing the Axe yourself, or
- Command your companion to attack using the companion command.
The achievement Dust Buster requires shattering all petrified Spider Kids with the Axe.
Spider Kid #1
After obtaining the Axe inside the Metro train, don't immediately follow the obvious route.
Use the companion boost to reach the roof of the Metro carriage.
Walk toward the front/screen area near the hatch.
Destroy the petrified Spider Kid.
Spider Kid #2
Drop into the foreground passenger carriage.
Search the interior aisle before continuing through the train puzzle route.
Destroy the second Spider Kid.
Spider Kid #3
After reaching the next Metro platform, check the right-side safety railing near the train exit.
Destroy the petrified Spider Kid there.
Metro Train Puzzle
The train section contains an alignment puzzle involving letters.
Move through the train cars and manipulate the relevant positions until the required O-D alignment is restored.
Once the letters are correctly aligned, the train route can continue toward the next station.
Puzzle tip
If you're unsure where to go, focus on the visible lettering rather than trying to force the next door.
The correct alignment is the progression trigger.
Poster #5 and the Elevated Walkway
After reaching the next Metro platform, search the opposite side before continuing.
Super Fly Poster #5
From the train exit, cross toward the front-left corner of the platform.
The poster is mounted on the structural pillar/wall in that area.
It's easy to walk straight past it while following the main route.
Stalking Shadow
Continue onto the elevated walkway.
Before using the squeeze door, check the concrete wall directly to its left.
Use the camera flash on the hidden silhouette.
Keycard Location
Eventually you'll reach the security area.
Search the room carefully before leaving.
The Keycard is required for an important secret achievement.
Once you've picked it up, you might naturally continue forward.
Don't.
This is where the DLC expects you to backtrack.
Into the Dark: White Rabbit Secret
This is arguably the easiest achievement in the DLC to miss if you follow the main path without exploring.
The achievement Into the Dark requires releasing the dying rabbit from its painful end.
How to unlock Into the Dark
Step 1 — Get the Keycard
Reach the security room and pick up the Keycard.
Step 2 — Turn around
Do not simply continue toward the next objective.
Return through the narrow squeeze route you previously used.
Step 3 — Return to the previous Metro station
Backtrack all the way to the earlier subway platform.
Step 4 — Drop onto the tracks
Go down to the subway tracks.
Look along the darker side of the track area for the locked security door.
Step 5 — Use the Keycard
Interact with the electronic card reader.
The locked door opens.
Step 6 — Follow the hidden corridor
Walk through the dark passage until you reach the small room at the end.
Step 7 — Interact with the White Rabbit
Approach the White Rabbit and interact with it.
This triggers Into the Dark.
The important part
The Keycard is not the achievement.
The achievement requires completing the entire sequence:
Keycard → backtrack → previous tracks → locked door → White Rabbit → interact
If you simply pick up the Keycard and continue forward, you'll miss the opportunity until you return.
Metro Ticketing Hall
After completing the White Rabbit sequence, return to the main progression.
Continue toward the ticketing area.
You'll need to restore power before the turnstiles can be used.
Turnstile power puzzle
Locate the circuit breaker and restore power.
Once the system is active, you can operate the turnstiles and enter the ticketing hall.
Don't rush through this area.
There are several final collectibles nearby.
Final Collectibles and Bridge
Super Fly Poster #6
After passing through the turnstiles, look toward the right-hand wall of the ticketing hall.
The final Super Fly Poster is located there.
Collect it before heading up the stairs.
Spider Kid #4
Inside the ticketing hall, search the back wall beneath the large station clock.
Destroy the petrified Spider Kid.
Stalking Shadow #6
After leaving the station, check the roof of the abandoned civilian sedan immediately to the right of the outdoor stairwell.
Use the camera flash.
Spider Kid #5
Check the passenger-side door/frame of the same vehicle.
Destroy the petrified Spider Kid.
Blood Hound Suitcase #6
Search behind the abandoned sedan near the crashed delivery truck.
Open the suitcase and flash the red symbol.
This completes the Blood Hound sequence.
Spider Kid #6
Continue toward the final elevated bridge.
Look for the crashed vehicle frame.
The final petrified Spider Kid is leaning against the wreck.
Destroy it with the Axe or companion command.
If you've followed the guide, this completes the Spider Kid set.
Final Bridge Sequence
Continue along the main bridge route.
The final section is largely focused on progression rather than exploration.
Cross the crumbling pillars and finish the sequence.
Completing the DLC awards One Down, which is the main completion achievement for The Prisoner.

Commonly Missed Secrets
If you're going back through the DLC because something is missing, check these locations first.
1. Poster behind the clothing rack
The entrance isn't obvious.
Look for the clothing rack inside the apparel store and crouch through the hidden opening.
2. Poster behind the bookshelf
The bookshelf isn't simply decoration.
Use the unexploded grenade to destroy it and reveal the hidden route.
3. Arcade
The arcade is accessed through an environmental puzzle rather than the main path.
It also contains the Space Suit / Astronaut Helmet Mask and a Stalking Shadow.
4. Fireplace chairs
Both characters need to sit down.
Don't move immediately after sitting.
5. Crater chair
Stay on the crater's narrow rim instead of dropping into the main area.
6. Exploding suitcases
These are intentionally dangerous.
If you're going for all achievements, you actually want to trigger them.
7. White Rabbit
This is the biggest route trap.
Get Keycard → turn around → return to previous tracks.
REANIMAL The Prisoner DLC FAQ
How many achievements does The Prisoner DLC have?
There are 10 DLC achievements/trophies worth 315 Gamerscore.
How do you unlock Into the Dark?
Get the Keycard in the security room, backtrack to the previous Metro station, drop onto the tracks, use the Keycard on the locked door and interact with the White Rabbit.
Do Blood Hound suitcases need the camera?
Yes. Opening the suitcase is not the complete interaction. Open it and use the camera flash on the red symbol inside.
What are the exploding suitcases for?
They are traps associated with Definition of Insanity. You need to trigger both traps and survive the resulting respawns to complete the achievement requirement.
Do you need the Axe for the Spider Kids?
Yes. The petrified Spider Kids are destroyed using the Axe, either directly by the player or through the companion command.
Can I get the achievements in solo play?
Yes. REANIMAL supports single-player as well as local and online co-op, and companion commands can be used when playing alone.
What is the easiest collectible to miss?
The White Rabbit sequence is one of the easiest secrets to overlook because it requires deliberate backtracking after obtaining the Keycard.
The hidden posters behind the clothing rack and bookshelf are also easy to miss if you follow the main route.
