Bendy and the Ink Machine Unlikely Victory Walkthrough

How to Unlock Unlikely Victory

Bendy and the Ink Machine unlikely victory turns Chapter 4’s final showdown into a fight with a plunger. The crucial preparation happens before the boss arena, so collecting the hidden machine dial saves you from reaching Boris with the wrong equipment. To earn Bendy and the Ink Machine unlikely victory, restore power to the Haunted House, return to upper Maintenance for the dial, and use plungers to defeat Boris and finish the chapter.

The achievement belongs to Chapter 4: Colossal Wonders. Its challenge connects a secret pickup with the chapter’s final weapon-crafting sequence. Simply reaching the boss or producing a regular pipe does not fulfill the plunger objective.

Keep these related achievements separate while planning your run:

Achievement	How to unlock
Unlikely Victory	Complete Chapter 4 with the plunger
A Haunting We Will Go	Restore power to the Haunted House
Reunited	Reach the reunion with Boris at the beginning of the boss battle

The important connection is between the Haunted House power objective and the hidden dial. Restoring power gives you a reason to revisit Maintenance before continuing toward the finale.

Spoiler warning: The walkthrough below covers the hidden dial and all three phases of the Boris fight.

Find the Hidden Dial Before Entering the Haunted House

For the Bendy and the Ink Machine unlikely victory route, return to upper Maintenance after restoring power to the Haunted House and before entering it. The trunk holding the dial cannot be opened during your earlier visit to Maintenance.

Complete the tasks required to power the Haunted House, then pause before entering it. The wall message telling you to turn back points toward the backtracking needed for this secret.

Follow this sequence:

1. Restore power to the Haunted House. Finish the required side tasks until its entrance opens.
2. Leave the Haunted House entrance for later. Return to Maintenance instead of advancing inside.
3. Go to the upper area. Look for the switch and the trunk on the ground nearby.
4. Open the trunk. Collect the dial inside.
5. Return to the Haunted House. Continue toward the ride and the Boris encounter.

Use the following landmarks to keep the detour focused:

Landmark	What to look for	What to do
Haunted House entrance	The entrance after power has been restored	Turn back before entering
Maintenance	The upper area	Return to the switch
Ground near the switch	A trunk that was previously locked	Open it and collect the dial
Boris arena	The crafting machine’s right side	Replace its existing dial

The plunger itself is crafted later. Your objective during this detour is to collect the part that changes what the boss-room machine can produce.

Before leaving upper Maintenance, check that you actually collected the dial rather than merely opening the trunk. Keep that pickup as a separate item on your mental checklist: power restored, trunk opened, dial collected.

You can also handle A Little Souvenier during your visit to upper Maintenance. Stand behind the photo cutout, aim at the camera, and wait for its flash. Finish that optional stop before returning to the Haunted House.

Set Up the Machine and Craft Your Plungers

Once the Boris battle begins, take the hidden dial to the crafting machine. Install it on the right side, replacing the existing dial, then turn it to select plungers.

This is the equipment change that makes Bendy and the Ink Machine unlikely victory possible. The trunk supplies the selector; Boris supplies the glowing ink needed to manufacture your weapons.

Component or action	Purpose
Hidden Maintenance dial	Replaces the boss-room machine’s existing selector
Plunger selection	Sets the machine to produce the achievement weapon
Glowing ink blob	Supplies material for crafting
Machine output	Provides a plunger to collect and use against Boris

Do not stop after inserting the replacement dial. Turn it to the plunger setting before using the ink. Otherwise, you have completed the hidden-item detour without finishing the machine setup.

During the opening phase, dodge Boris until he clutches his chest and produces a glowing ink blob. Collect it, deposit it in the machine, and craft your weapon. Pick up the plunger before returning to the fight.

Each plunger lasts for one successful hit. The battle requires another crafting cycle after each of the first two hits, using the next blob Boris drops.

Keep the loop clear:

• Dodge until the required opening.
• Collect the glowing ink.
• Use the machine to make a plunger.
• Pick up the weapon.
• Land the hit appropriate to the current phase.

Plan your movement around both Boris and the crafting station. Because the weapon must be replaced between phases, chasing him constantly only distracts you from the next required interaction.

For Bendy and the Ink Machine unlikely victory, keep checking the actual weapon you collect. The achievement depends on completing the encounter with plungers, so the machine’s selected output deserves your attention every time you craft.

Beat Boris Through All Three Phases

The fight changes after each successful plunger strike. Watch the attack pattern rather than trying to repeat the opening phase’s timing throughout the encounter.

The detailed sequence below follows the v1.5.1.0 battle. Update 2.1.0 increased the plunger’s weapon range and added continuous attacks while holding the attack button. It also fixed an issue that could make the Gent Pipe unbreakable during the Boris fight.

Those updates improve weapon handling, but your achievement route still centers on the hidden dial and plunger crafting.

Phase	Boris’s attack pattern	Your response
First	Follows you and charges when you move farther away	Dodge until he drops ink, craft a plunger, then sidestep a charge and strike
Second	Launches upward and slams down toward you	Keep moving, craft a replacement, and hit him while he is on the ground
Third	Retrieves carts and throws them from the middle of the room	Dodge three carts, then strike when he weakens

First Phase: Dodge the Charges

Boris follows you around the arena and charges when you create distance. Move aside as he commits to a charge, then prepare for the next one.

After several dodges, he grabs his chest and produces the first glowing ink blob. Take it to the machine and make your opening plunger.

Once armed, sidestep another charge and hit Boris. That successful strike advances the fight and uses up the weapon.

Tip: Separate the ink-collection task from the attack task. First secure the material and craft the plunger; then concentrate on lining up your counterattack.

Second Phase: Keep Moving Through the Slams

After the first hit, Boris drops another ink blob. Use it to manufacture your next plunger while responding to his new attack pattern.

He now rises into the air and slams down toward you. Keep moving instead of waiting beneath him. During this phase, you can hit him whenever he is on the ground.

Take the grounded opening with your replacement plunger. The successful hit advances the fight again and provides the next blob for crafting.

Avoid applying the charge-phase rhythm here. Your visual cue is Boris returning to the floor, giving you a different opening from the one you used previously.

Third Phase: Dodge the Carts Before Closing In

Craft the final plunger from the ink dropped after your second successful strike.

Boris moves to the back of the room, picks up carts, returns toward the middle, and throws them at you. In the v1.5.1.0 encounter, a cart hit causes instant death.

Prioritize dodging over approaching. Let the three cart throws play out, then move in when Boris weakens and land the final plunger strike.

The final stretch of Bendy and the Ink Machine unlikely victory rewards patience. Keep your attention on the thrown carts until the vulnerability window arrives, even with the last weapon ready.

After defeating Boris, continue through the chapter’s ending to complete the achievement objective.

Plan Your Chapter 4 Achievement Cleanup Order

Combine the plunger route with other Chapter 4 objectives by handling each achievement when its location or encounter becomes relevant. This keeps the Maintenance return trip purposeful and prevents optional tasks from crowding your attention during the finale.

For a Chapter 4 completion run, use this order:

Point in the chapter	Achievement objectives	Required action
Before entering Archives	Barbecued	After opening Archives, return to Management and enter the previously locked room to find the hidden poster
After opening the PRIVATE door	Finger Waggin	Use the machine’s radio-shaped selection, supply ink, create the radio, and turn it on
Carnival games	Bulls Eye; Call The Milk Man; Wasting Time	Earn perfect scores in the shooting and bottle games, and ring the strength-test bell
Bertrum encounter	Going To Be Sick; Around And Around	Ride an available seat during an exposed-arm opening, then defeat Bertrum
Maintenance	A Little Souvenier	Stand behind the photo cutout and trigger the camera
Haunted House power restored	A Haunting We Will Go; plunger preparation	Return to upper Maintenance and collect the hidden dial
Throughout Chapter 4	Just Like Mom Used To Make; Still Listening	Collect the chapter’s Bacon Soup and listen to its audio logs
Boris encounter and chapter ending	Reunited; Unlikely Victory	Reach Boris, use the replacement dial, and finish with plungers

For Bulls Eye, practice the target sequence: the positions stay the same, and a perfect attempt requires every shot to connect. For Call The Milk Man, knock down all nine bottles using three balls.

Keep the Bertrum ride achievement in mind before destroying every arm. When an arm comes down and exposes its weak points, interact with a seat to take the ride.

For Bendy and the Ink Machine unlikely victory, the final preparation checkpoint remains the same: collect the Maintenance dial before entering the Haunted House. Finish nearby optional objectives, check the trunk pickup, and head into the finale ready to craft.
