In this guide, I show the locations of all 12 jigsaw pieces in We Were Here Tomorrow. I follow the route through the Common Room, Research & Development, Prototype Room, and other areas to find each piece. I explain where to look and how to reach the collectibles, including an important warning about the lever in the room before the funicular.
All 12 Puzzle Pieces Locations
Common Room (the Hub) – Jigsaw Piece 1 to 4
Puzzle Pieces #1 to 3
I find the first three pieces under the small table with the half-finished puzzle on it.

Puzzle Piece #4
Then I look on the dining table with the cakes, next to the test tubes and notepad, to find the next piece.

Research & Development Jigsaw Pieces 5 and 6
Puzzle Piece #5
I enter the two-story room with two key card slots, which later leads to the Prototype Room.

Then I head underneath the second floor and look on the laboratory counter to the right of the entrance.
Puzzle Piece #6
I go to the second floor and check the small cabinet just to the left of the stairs.

Prototype Room – Jigsaw Piece 7
Puzzle Piece #7
I take the elevator to the first platform or use the platforms to climb up. The piece is on the left ceiling fan.

I use the hook player to grab the piece without stopping the fan. The cube player can gum up the fan first, but this isn’t required.
Small Room – Jigsaw Piece #8
Puzzle Piece #8

I finish the Prototype tutorial, enter the small room, and pull the lever together with my partner. I then leave through the door.

Then I find the piece on the table to the right of the entrance.
Common Room (the way back to the Hub) – Jigsaw Piece 9
Puzzle Piece #9

For the ninth piece, I go through the door to the left of the table where I found piece #8 and climb the stairs.

I continue towards the boxes and look for the one with a hard hat on it. The piece is right next to it.

The room before the funicular – Jigsaw Piece 10
Puzzle Piece #10
Important: Do not pull the dual-handled lever in the center of the room. Doing so will lock the door leading back to the Hub / Common Room with the jigsaw puzzle.

I climb to the second floor using the route shown in the screenshot and look to the left, where I find a computer panel in front of the locked Control Room. The piece is sitting on top of the panel.

The Hub Balcony – Jigsaw Pieces 11 and 12
Puzzle Piece #11
For the 11 Puzzle Piece, I use the door on the same floor as piece #10 to reach the balcony.

I look to the right and find a computer with a small cabinet to its left. I check the cabinet to collect the next piece, then stay where I am.
Puzzle Piece #12
I turn to face the Common Room and look up at the ceiling lights to find the last piece.

The piece is missing from the screenshot, but its exact location is marked.
