Bendy and the Ink Machine Going to Be Sick: Unlock Guide

How to Unlock Going to Be Sick

Bertrum’s boss arena hides an achievement inside the ride trying to crush you. To unlock Bendy and the Ink Machine Going to Be Sick, interact with a passenger seat during the Chapter 4 Bertrum Piedmont fight when one of his arms is resting on the ground. The key to Bendy and the Ink Machine Going to Be Sick is using that opening to board the ride before focusing on its exposed joints.

The achievement’s short description points you toward a ride, but the important detail is the seat interaction. Approach the lowered cart and use your interaction control to climb aboard. Simply attacking the arm or jumping onto the machinery is not the required action.

Achievement detail	What you need to know
Platform	Steam-exclusive achievement
Chapter	Chapter 4
Encounter	Bertrum Piedmont in Attraction Storage
Unlock action	Interact with a seat and ride Bertrum
Timing	While an arm is lowered during the fight

This is a separate objective from defeating Bertrum. You can finish the boss encounter without boarding, so put the ride interaction ahead of your normal attack routine.

The boarding sequence can only be performed once during the encounter. Aim to make that interaction your priority when a seat becomes accessible, then return your attention to dismantling the boss.

Reach Bertrum in Attraction Storage

Your destination is Attraction Storage, where activating Bertrum’s audio log starts the boss fight. This encounter is part of Chapter 4’s work toward restoring power to the Haunted House.

The audio log and the axe are closely connected to the beginning of the fight: the axe is inside the crate associated with the recording that triggers the encounter. Pick it up for the battle, but remember that the achievement itself comes from boarding a seat.

Use this sequence to keep the setup straightforward:

1. Progress through Chapter 4 until you reach Attraction Storage.
2. Activate Bertrum’s audio log to begin the encounter.
3. Pick up the axe from the crate.
4. Watch for an arm to slam down and expose its circular joints.
5. Approach a passenger seat on the lowered ride section.
6. Interact with the seat to board.

For Bendy and the Ink Machine Going to Be Sick, reaching the vulnerable arm is only the setup. The action that matters happens at the seat.

Do You Need the Axe Before Boarding?

For Bendy and the Ink Machine going to be sick, the axe is your weapon for destroying Bertrum’s exposed joints, but it is not the boarding requirement. You can enter a seat without holding it.

Pick it up before settling into the fight so you are ready to continue afterward. Just avoid confusing weapon preparation with the achievement trigger: swinging at a seat will not replace interacting with it.

Accessing Chapter 4 in Version 2.1.0

Version 2.1.0 unlocks every chapter except the Archives regardless of story progress. That makes Chapter 4 accessible without requiring you to unlock all preceding chapters first.

Once inside the chapter, your destination remains the same: reach Attraction Storage and prepare for the Bertrum encounter.

Use the Lowered-Arm Opening to Board

Bertrum’s lowered arms create an opening for two different actions. You can attack the exposed joints to advance the boss fight, or approach a seat to take the ride.

For this achievement attempt, choose the seat interaction before working on the joints.

Encounter moment	What to look for	What to do
Fight begins	Bertrum becomes active after the recording	Collect the axe and watch his arms
Arm slams down	A ride section rests near the ground	Locate a passenger seat
Joints become exposed	Circular weak points are visible	Approach the seat before attacking
Seat is within reach	You can target the passenger seat	Use your interaction control
Boarding succeeds	You ride Bertrum	Complete the ride interaction for the achievement

The vulnerable phase is useful because it brings the cart within reach. Focus on the passenger compartment rather than the mechanical joints beside it.

Bendy and the Ink Machine Going to Be Sick rewards a brief change in priorities. During an ordinary boss attempt, those exposed joints invite immediate axe swings. During an achievement attempt, they signal that it is time to look for a seat.

Interact With the Seat Instead of Jumping

Treat boarding as an object interaction. Move up to the seat, aim at it, and use the interaction control assigned in your setup.

Jumping onto a lowered arm is a different action. The unlock condition is riding in the cart, so concentrate on entering the seat rather than balancing on the attraction.

Avoid guessing a keyboard key from another player’s setup. Use your configured interaction control, whether you are playing with a keyboard or controller.

Separate Boarding From Boss Damage

Keep the achievement objective simple:

• Watch for the arm to lower.
• Find the passenger seat.
• Interact to board.
• Return to attacking the joints afterward.

This order keeps the optional interaction ahead of the actions that finish the encounter. You do not need a special attack combination or a particular amount of damage to enter the ride.

Avoid Mixing Up the Achievement Conditions

The name sounds like a clue about nausea, but the requirement is a specific interaction during Bertrum’s fight. Keep your attention on the attraction’s seats.

Several nearby actions belong to the same encounter without satisfying the same objective.

Action	Purpose
Activate Bertrum’s audio log	Starts the boss encounter
Pick up the axe	Prepares you to damage the exposed joints
Interact with a passenger seat	Boards the ride for Going to Be Sick
Destroy Bertrum’s arm joints	Defeats the boss for Around And Around

The distinction matters because Around And Around is the boss-defeat achievement. Bendy and the Ink Machine Going to Be Sick is the optional ride achievement inside that battle.

Do Not Leave Boarding Until After the Fight

Complete the seat interaction while Bertrum is active and an arm is lowered. The achievement’s boarding opportunity belongs to the fight itself.

Put it ahead of destroying all the joints. Finishing the encounter first reverses the order you need for this optional objective.

Keep Old Bugs Separate From Current Patch Changes

The original 2018 version had a ride-related problem that could leave Henry stuck above the attraction and require closing the game.

Version 2.1.0 includes fixes for various softlocks, crashes, collision problems, and situations where players became stuck in unintended locations. Those changes are broader than this single achievement.

Use an updated installation before attempting cleanup. If you are playing an older build, keep that historical stuck-state issue in mind when boarding Bertrum.

Finish Bertrum and Plan Chapter 4 Completion

After the ride interaction, continue the encounter by attacking Bertrum’s exposed joints with the axe. Each of his four arms has four joints to destroy.

Wait for an arm to slam down, then attack its vulnerable circular joints. Work through all four arms to finish the fight and unlock Around And Around.

Bendy and the Ink Machine Going to Be Sick fits naturally before that boss-defeat achievement. Handle the seat first, then return to the combat objective.

For a broader Chapter 4 achievement run, organize optional actions around the areas you pass through. This keeps the Bertrum ride from becoming an isolated cleanup task later.

Achievement	How to unlock
Barbecued	Visit theMeatly behind the poster in the room accessible after opening the Archives
Finger Waggin	Create a radio with the ink machine and turn it on
Bulls Eye	Earn a perfect score on Bull’s Eye Bonanza
Call The Milk Man	Earn a perfect score on Bottle Wallop
Wasting Time	Ring the bell on the strength-testing game
Going To Be Sick	Board a seat during Bertrum’s fight
Around And Around	Defeat Bertrum
A Little Souvenier	Stand behind the photo cutout and aim at the camera
Unlikely Victory	Complete Chapter 4 using the plunger for the final boss fight

Chapter 4 Completion Order

Use this order when working toward full Chapter 4 achievement completion:

1. Handle the early secret. After opening the Archives, return toward Management and enter the newly accessible room to find theMeatly behind the “SHEEP SONGS!” poster.
2. Create the hidden radio. At the machine beyond the “PRIVATE” door, select the radio-shaped dial setting, deposit an ink blob, pull the lever, and turn on the radio.
3. Complete the carnival challenges. Pursue perfect scores on Bull’s Eye Bonanza and Bottle Wallop, and ring the strength-test bell near Research and Design.
4. Board Bertrum before defeating him. Enter a seat during the lowered-arm opening, then destroy the joints to finish the encounter.
5. Handle Maintenance extras. Listen to the audio log in the back-left area and use the photo cutout upstairs.
6. Prepare the plunger objective. After opening the Haunted House, return to upper Maintenance for the dial inside the trunk near the switch. Use that dial at the machine in the final boss encounter to produce plungers.
7. Track collectibles throughout the chapter. Collect Bacon Soup and listen to audio logs along the route rather than postponing them until the end.

Keep the Bertrum portion of that checklist short: board, ride, then break the joints. That sequence covers both achievements tied directly to his encounter.
