About In Sink: A Co-op Escape Adventure
In Sink: A Co‑op Escape Adventure drops two players onto a shipwrecked start that quickly expands through portals into a series of themed worlds. Each of the eight levels, from a hidden pirate ship to a physics‑defying train, is built around colour‑blind‑friendly puzzles that require partners to act as each other’s eyes and ears.
The game uses simple, accessible controls and a dynamic hint system that offers assistance without revealing full solutions. It supports full controller use, online co‑op, Steam Achievements, Steam Cloud and Family Sharing, making it approachable for casual and indie‑game fans alike.
01 / THE GUIDE
Co‑op Gameplay
Two players work together online to solve escape‑room style challenges across eight distinct levels. Success depends on communicating observations and coordinating actions such as turning wheels, flipping levers, and pressing pressure plates.
The design stresses staying “in sink” with your partner, meaning each player must relay visual information to complete language‑free puzzles that rely on shapes, signs, colours and numbers.
- Speak aloud about the shapes and colours you see to keep both players aligned.
- Assign one player to handle levers while the other manages wheels to avoid overlap.
02 / THE GUIDE
Puzzle Design
Puzzles are built from language‑less elements like shapes, signs, colours and numbers, and are described as colour‑blind friendly. Players manipulate wheels, levers, scales and pressure plates to progress.
A dynamic hint system provides help without spoiling solutions, preserving challenge while preventing frustration.
- Observe patterns in shapes before interacting with mechanisms.
- Use the hint system early if you feel stuck to maintain momentum.

Level Variety
The eight levels span diverse settings: a hidden pirate ship, a mysterious art museum, and a train that defies the laws of physics, among others. Each environment introduces new visual themes and puzzle mechanics.
Portals link the shipwrecked start to each subsequent world, serving as transitions between the varied settings.
- Take a moment to explore each new setting for visual clues.
- Notice how each world’s theme hints at the type of puzzle you’ll face.

Controller Support
The game offers full controller compatibility, including DualShock and DualSense support, allowing players to use gamepads for all interactions such as lever pulls and button presses.
Steam Cloud and Family Sharing are also supported, enabling progress synchronization across devices and shared access between accounts.
- Map controller buttons to frequently used actions for quicker response.
- Enable Steam Cloud to keep co‑op progress safe when switching PCs.

Achievements & Multiplayer
Playing online co‑op unlocks Steam Achievements tied to completing specific puzzles or finishing levels without using hints.
The game lists Online Co‑op and Multi‑player as features, confirming that two players can connect over the internet.
- Aim for achievement milestones by avoiding hints on early levels.
- Coordinate playtimes with your partner to ensure a stable online connection.
