The red room with soundproof glass in Big Walk drops a physical barrier between you and your partner, cutting off normal voice chat right when you need to trade information the most. Beating it means one player reads a symbol order while the other rebuilds it, with the glass forcing you to rely on walkie-talkies or gestures. Clear it and you can carry the gourd up to the Green Tower.
Quick answer: Press the two buttons in opposite corners to release the gourd and raise the glass, then have the trapped player near the symbol board direct their partner to a hidden button behind a wooden beam. Pressing it unlocks the caged board and opens a terminal showing the correct symbol order. Match that order on the board, press the button under the black screen, and the glass drops.
Where to find the soundproof glass red room
The red house structure sits on the southern side of the Green Tower. From the top of the tower you can spot it out across the landscape, and it lands just past the blue monitors on poles counting puzzle. Head toward that marker and step inside the red building to begin.
Tip: Bring at least two walkie-talkies split between you and your teammates before you start. Voice chat won’t carry through the glass, and a walkie-talkie is the fastest way to pass the symbol order once the barrier goes up.
Start the puzzle and raise the glass
Unlock the caged symbol board
Pressing that hidden button does two things at once. It unlocks the caged symbol board so the pieces can be moved, and it pops up a terminal on the opposite side of the room that displays the correct order of symbols.
Pass the symbol order through the glass
Only one player sees the terminal with the symbol order, and only the other player can arrange the board. Since the glass blocks voice chat, you have two reliable ways to bridge that gap.
| Method | How it works |
|---|---|
| Walkie-talkies | The player at the terminal reads out the symbols in order, and the player at the board sets them. This is the quickest and most reliable route. |
| Gestures | The player at the board picks up individual symbol pieces and holds them up using E and Q on keyboard, or LT/L2 and RT/R2 together on controller. The player at the terminal nods yes or no to confirm each one. |
Confirm the order and drop the glass
Once the board matches the order shown on the terminal, press the button under the black screen to submit. If the sequence is correct, the soundproof glass lifts and you’re free to grab the gourd and haul it up to the Green Tower.
If the glass stays put, the symbols are in the wrong order. Recheck the terminal reading, adjust the board piece by piece, and press the button again. The barrier only clears on a fully correct match, so a single misread symbol is the usual reason it fails.
With the gourd in hand, you’re one collectible closer to shaping the Green Tower key. Carry it to the tower and add it to the others you’ve gathered from the surrounding Green Tower puzzles.
