Shred the Secrets Secret Locations: Every Collectible

The key is inside one of the filing/storage lockers in Room 3 — open every single locker, not just the obvious ones, and it eventually drops. It unlocks the closed-off area where the Sketchy Coworker (and the phone quest) wait. Footage-verified.

A glowing EXIT door tucked behind the paper stacks in Room 4 — no key needed, just walk up and open it, and the badge pops (21.5% of players). It is a trap, not an exit: it awards Tricked! and leaves you in the office.

The phone lies on the floor in Room 3, behind the shredders next to the paper stacks by the locker area (17.7%). First unlock the closed-off area with the Room 3 key to meet the Sketchy Coworker, then pick up the phone on the floor behind the shredders — "It was here the entire time". Follow the full phone location and Room 3 key route, then return it for the Let's keep this between us badge. One community video links the return to the Golden Shredder; that obtain route is unverified alongside an alternate shredder-upgrade theory.

Community sources disagree on how you obtain the Golden Shredder: one video ties it to returning the Sketchy Coworker's phone, another to upgrading the shredder line — both are unverified. Once obtained, hold interact on any shredder to install it; that machine shreds six stacks per pass for double cash with no cranking. One shred session on it awards Solid Gold (15.2%).

Enter via the boarded-up doorway under the Room 6 cobweb room (crowbar required). Brew a pot at the coffee machine under the framed blueprint poster (2 minutes, "Take the coffee machine. The fresh pot will be ready in 2 minutes"), then get everyone into the elevator cabin to ride out (8.4%). Drinking the coffee grants a shredding speed burst.

The doorway sits at the bottom of the Room 6 cobweb room and leads to the basement. Pick up the crowbar in the same room (current version: on the recycling bin on the upgrade counter), then break every single plank — not just enough to pass — for the badge (5.3%). Footage-verified.

A wall prompt in Room 5 reads "Find the hidden buttons in the room to unlock the secret document". The 4 buttons glow green between the paper-stack columns — clear every second column to spot them, and a wall counter tracks your progress. All 4 open the side room holding the golden document (spoiler: a grocery list — pickles, cheese, milk, cat food, toilet paper) and start the Ending 1 chain.

A framed "THE CAKE IS A LIE" poster (a Portal reference) hangs on a dark wall between the paper stacks in Room 10, the testing lab added in the [ENDING 3] update. Walk up and interact with the painting for the badge (2.1% of players).

Badge text: "You weren't supposed to see that" (9.2%). Its location is UNKNOWN — it is not published anywhere, and no source explains what the hidden discovery is or where. Community suspects a hidden readable document, with the basement as the prime candidate — unconfirmed. Listed honestly as unknown, not as a fact.
