We Were Here Tomorrow Walkthrough: Every Puzzle Solution & Co-op Guide

Complete We Were Here Tomorrow walkthrough: every puzzle solution, key card, gadget, and co-op tip from the opening area to the Exotic Matter Lab.

This We Were Here Tomorrow walkthrough covers every puzzle from the frozen opening area to the roller coaster arrival at the Exotic Matter Lab, so you and your partner never stall in front of a locked door. We Were Here Tomorrow is the newest entry in Total Mayhem Games' two-player co-op puzzle series, and like every game before it, it splits you and a partner into separate rooms where your only tools are a walkie-talkie, your voice, and whatever cryptic symbols are painted on the walls. Because each puzzle hides half of its solution on the other player's side, a reliable walkthrough is the difference between a smooth ninety-minute run and an hour of shouting "which lever?!" into your microphone.

How We Were Here Tomorrow Works: Roles, Gadgets, and Ground Rules

Every game in the series is built on asymmetric information: one player sees the instructions, the other holds the controls, and neither can finish alone. That structure shapes this We Were Here Tomorrow walkthrough — every solution below is written as a two-part script covering who describes and who acts.

You start by picking roles, and community reports from early playthroughs note that the shapes on the role-select screen match the two gadgets you unlock mid-game, so your choice sticks for the whole run. You wake up in a frosty, retro-futuristic facility — a frozen crew member greets you at the door — and the emote wheel (T on PC, per player experience) stays locked until you progress. You can check the game and its requirements on Total Mayhem Games' official Steam page before dragging a friend into it.

Three ground rules will carry you through everything:

Describe what you see concretely ("a puffer fish inside a starburst"), never vaguely ("the spiky one").
Read every note, sign, and screen out loud — several solutions hide in plain text.
If a room feels empty, re-check it after progress; new interactions unlock as story beats advance.

Here's the full route at a glance:

Area	Puzzle	Describer does	Actor does
Opening	Symbol buttons	Reads three alien monitors	Presses buttons in order
Opening	Door power	Checks computer for the pattern	Activates lever, crank, slide bar
Opening	Battery run	Toggles doors	Delivers battery, pulls release
R&D	Circuit board	Describes component silhouettes	Places six shape plugs
R&D	Chemistry	Reads the hint note	Dispenses four chemicals
Mainframe	Timed dials	Calls out needle directions	Sets four dials on a timer
3D printer	Grid panel	Reads the dot target from a window	Moves cursor, locks positions
Gadget hall	Hook targets	Spots colored targets	Fires goop or pulls hooks

Opening Area: Symbol Codes, the Five-Switch Door, and the Battery Run

The opening stretch packs three puzzles back to back, and this We Were Here Tomorrow walkthrough keeps them in the order you'll actually hit them.

Puzzle 1: The Alien Symbol Buttons

The first real test is classic We Were Here. One player faces monitors showing alien imagery — a butterfly-shaped brain, a tentacled Cthulhu-like figure over an omega symbol, and a starburst with a puffer-fish face flanked by cogs. The other player sees three buttons and nothing else.

In our reference playthrough, the working order was the middle button (the tentacle/omega figure) first, then the starburst, then the butterfly. The broader lesson matters more than the answer: the describer should name every distinct element of each image before the actor presses anything.

Puzzle 2: Powering the Door — Five Switches, Three Answers

Next, one room holds five interactive objects: a button, a jump pad, a pressure gauge, a crank, a slide bar, and a large lever. Only three actually open the door, and the wires merge into a single line, so there's no obvious mapping.

The trick is the computer station in the partner's room. Player experience from early streams says the pattern — lever, crank, slide bar — only appeared on that monitor after the room's state changed. If the screen looks dead, progress something else and look again.

Puzzle 3: Door Swaps and the Pneumatic Battery

This sequence introduces the game's favorite co-op rhythm: one player toggles which door is open while the other runs. The runner grabs a battery pack, sends it through a pneumatic tube, then the toggler swaps the doors back so the battery reaches the correct socket. Finally, both players grab the release and pull together.

Tip: the toggler should swap doors immediately after the runner passes, without being asked. Hesitation cost our reference streamers a couple of comedic wrong turns.

R&D Wing: Key Cards, Shrinking, the Circuit Board, and Chemistry

The R&D wing is where this We Were Here Tomorrow walkthrough starts branching, because the area gates itself with key cards — yellow first, with green and blue arriving later in the run. Once inside, one player steps onto the matter reduction platform and shrinks to mouse size, then navigates a miniature route through bookshelves that the full-sized partner rearranges to clear a path. Community reports mention the shrink may run on a timer, so don't dawdle while tiny.

The wing's main puzzle is a circuit board. The actor holds six shape plugs — square, pentagon, plus, triangle, Y, and star — while the describer sees components resembling tandem bicycles and other odd silhouettes, each demanding specific shapes. Squares are green and triangles are red, which narrows placements fast.

There's some forgiveness here: in player experience, components slotted in and the circuit lit up section by section, so deliberate trial and error works. Still, describe the silhouette and socket labels first — it beats blind swapping every time.

The Chemistry Dispenser Order

The chemistry puzzle is the meanest in the demo because the hint arrives after you've already made a mess. One player controls a dispenser with three chemicals — acrylonitrile, butadiene, and styrene — while the other hunts for a note explaining that a mix of one part acrylonitrile with an equal part of butadiene produces the right compound, but the batch distills and ruins itself unless styrene bookends the process, added both before and after.

If you botch it, use the extraction machine to suck the mixture out and start clean.

Step	Chemical	Why
1	Styrene	Must come first to prevent distillation
2	Acrylonitrile	The "one part" from the hint
3	Butadiene	The "equal part" from the hint
4	Styrene	Must come last to prevent distillation

Sharp-eyed chemistry fans will notice those three monomers combine into ABS — the same plastic real-world 3D printers use. The game is quietly telling you where the story goes next.

Mainframe: Floppy Disks, Timed Dials, and the 3D Printer Escape

Inside the mainframe, two deactivated buttons and two giant floppy disks labeled 01 and 02 block the path, while a monitor requests a save disk. The solution: the shrunken player teleports back, enlarges on the matter platform, and inserts the save disk while the partner opens doors along the way. This is the point where a We Were Here Tomorrow walkthrough earns its keep, because nothing in the room tells you the tiny player needs to be big again.

That activates the dial puzzle. Pulling a lever spins four dials that stop after a moment, so the describer must read needle directions fast while the actor sets them. The two reported sets:

Set	Dial 1	Dial 2	Dial 3	Dial 4
First	Right	Up	Up	Left
Second	Upper-left	Bottom-left	Upper-right	Upper-right

Wait for the full rotation between sets, and have the describer pre-read everything before pulling. Meanwhile, don't skip the care sheet posted nearby: Clive — evidently a rodent — requires a documentary channel on the TV, a strict gluten-free diet, a freshly oiled wheel, and absolutely no access to the matter reduction or enlargement platform. Someone clearly learned that lesson the hard way.

The 3D Printer Grid Puzzle

After the dials, the shrunken player pops out of a 3D printer. One player then watches a dot target through a window while the other moves a cursor on the grid panel behind the printer, locking each position with the middle button.

The reported sequence: up three times, right twice (lock), left once (lock), down once, right once (lock), down twice (lock), left once (lock). The real enemy is perspective — "your left" and "my left" caused several wrong moves in our reference run, so agree on whose viewpoint you're using before the first move. Done correctly, the printer produces a green access pass that opens the way forward.

Goop Guns, the Roller Coaster Finale, and Time-Saving Co-op Tips

A sign warning "do not goop your colleagues" introduces the run's best toys: one gun fires goop, the other deploys solid cubes. Three target puzzles follow, all built around hooks you pull with F.

Target	Solution reported by players
Yellow	Straightforward hook pull from ground level
Blue	Climb up — place a cube as a step or take the alternate route
High target	Aim the goop gun upward; it shoots at steep angles

After the third target, power unlocks and a cube-sorting handle pull wraps the section. Then comes the payoff: a roller coaster whose car splits in two mid-ride, penguins watching from the snow, and a looming Sauron-like eye over the track. You disembark at the Exotic Matter Lab — the cliffhanger where this slice of the We Were Here Tomorrow walkthrough ends.

Co-op Tips That Actually Save Time

Common mistake	Why it hurts	Fix
Vague descriptions ("the squiggly one")	Partner guesses wrong	Use concrete comparisons: "puffer fish in a starburst"
Not agreeing on perspective	Left/right errors in grid puzzles	Say "your left" or "screen left" every time
Talking over each other during timers	Missed dial windows	One person calls, one acts, then swap
Skipping environmental text	Missing hint notes like the chemistry sign	Read every note aloud before experimenting
Random trial-and-error first	Wastes time and muddies clues	Describe all options, then test deliberately

Two more habits worth building. First, screenshot any diagram you find — the reference streamer photographed the chemistry settings and it paid off immediately. Second, treat this We Were Here Tomorrow walkthrough as a script you read to each other rather than a spoiler; when you're stuck, say what you've already tried out loud, because your partner often spots the contradiction before you do.

Frequently Asked Questions

Do both players need to own We Were Here Tomorrow? The experience is designed strictly for two players in separate rooms, connected by voice. Check the store page for the current friend's pass arrangement and platform requirements before you buy.

How long does this section of the game take? Based on community reports and our reference playthrough, expect roughly 60–90 minutes for the content covered here on a first run, and considerably less once you know the solutions.

Is this We Were Here Tomorrow walkthrough complete for the full game? This guide covers everything through the Exotic Matter Lab arrival, based on the demo build that community guides tracked in April 2026. Later chapters will need their own walkthrough as new content releases.

Can we play without voice chat? Technically yes, using text chat, but the timed dial puzzle and fast door swaps make voice communication close to mandatory. Any voice app works — the in-game walkie-talkie is flavor, not a requirement.
