Quick answer: how do you get Ending 3?
Ending 3 is the Whistleblower ending, added in the [ENDING 3] update (July 30, 2026). The run now spans 12 rooms — push past Room 8, then:
- In Room 9, find the ladder parts and repair the broken ladder to open the attic.
- Meet the Mad Scientist in the attic and take his quest: recover his blueprints. Completing it awards Industrial Revolution (3.4% of players).
- Clear through the Room 10 testing lab and Room 11 (Mesa Corp) to Room 12.
- Solve the bank vault dial — 4 turns; the room's note gives each turn's order (number) and direction (arrow).
- The vault opens, the Whistleblower (Ending 3) badge drops (4.9% of players), and the whiteboard reveal plays.
You can earn it solo — the source run below was a 1 hour 13 minute solo clear.

Push into the new rooms (Room 8 and beyond)
The [ENDING 3] update extends the run to 12 rooms. Ending 3 content starts at Room 8 — the floor is taped off with WARNING markings and the money goal climbs to $5,000,000 per room. Keep the usual loop going and clear a path forward.

Clear Room 9 and look up: the broken ladder
Room 9 is the green-lit room with the yellow catwalk. Above it sits a broken ladder — the game nudges you with "I can easily fix this ladder, right?" Find the missing ladder parts scattered around the room and repair it.

Repair the ladder to open the attic
With the parts collected, the ladder is fixed and the game announces "The attic has been opened." Climb up — your character wonders out loud what could possibly be behind this attic.

Meet the Mad Scientist in the attic
The attic hides an NPC in a lab coat — the Scientist. His chalkboard reads PROJECT: CAFFEINE, and he greets you with "Wait — you're not one of them." Talk to him to start his quest.

Take the quest: recover the Scientist's blueprints
The Scientist explains he helped make the sweetener in the coffee downstairs, tried to stop it, and got found out. He can undo it — but you must recover his blueprints, "vital parts of the machine," from the floors below. Finishing his quest awards the Industrial Revolution badge (earned by 3.4% of players).

Push through the Room 10 testing lab
Room 10 is the dark lab with red alarm lights and rows of orange chairs — your character mutters "This must be the human testing lab…" Keep clearing paper; the Golden Shredder's 2x cash, 6 stacks, no cranking pays for the $5M goals fast.

Walk into Mesa Corp (Room 11)
Room 11 drops the act: the wall logo reads MESA CORP — "THERE'S ALWAYS MORE WORK!" Your character realizes out loud: "Mesa Corporation..? I thought I was working for an accounting firm!"

Room 11: the company has a name — Mesa Corp.Watch at 6:50 - 8
Reach Room 12 and find the bank vault
The final room hides a bank vault door behind the paper stacks — "the conveniently placed bank vault door seems like it can be opened." Clear the paper in front of it and walk up to the dial.

Solve the vault dial — 4 turns, order and direction
Interact with the vault to start the dial minigame: TURN 1/4 up to TURN 4/4, with SPACE to give up. The room's note encodes the combination — each number gives the order of the turn, and its arrow points the direction to turn. Enter all four turns and the vault swings open.

Read the whiteboard — the boss's to-do list
The vault's whiteboard is the lore payload: "TAKE CARE OF THE ROGUE SCIENTIST / WASTE MORE PAPER / WASTE EVEN MORE PAPER! / FIGURE OUT HOW TO CONTROL THE WEIRD PEOPLE IN SUITS / THE SUIT PEOPLE SCARE ME / INSTRUCT ALL EMPLOYEES TO NOT GO INTO THE NEXT ROOM." The shredder cover-up goes higher than your boss.
