Play How 2 Escape: Lost Submarine on PC and Mac

How 2 Escape: Lost Submarine is a cooperative puzzle game developed by BreakFirst that puts two players on a mission to locate a missing submarine and stop a potential conflict from escalating into full-scale war. Designed as a companion experience, it pairs with the main game available on console and PC, and works seamlessly when you run it through MuMuPlayer on your computer for a more comfortable and controlled session.

The game is built entirely around two-player teamwork, requiring both participants to operate on separate devices while each takes on a distinct role in the mission. Puzzles grow progressively more demanding as you advance, and neither player can succeed without actively communicating and coordinating with the other. The asymmetric setup means each person holds different information and tools, making collaboration the core mechanic rather than an optional feature.

Playing the companion app through MuMuPlayer brings real advantages to the experience. Using a PC setup allows you to manage both your screen layout and your communication with your partner more efficiently, especially during complex puzzle sequences that require careful attention to detail. MuMuPlayer provides a stable and responsive environment that keeps the cooperative flow uninterrupted, letting you and your teammate focus entirely on cracking each challenge together rather than dealing with device limitations.

About the Game

How 2 Escape: Lost Submarine is not a solo adventure. It is a two-player cooperative puzzle experience where both participants must work in tandem across separate devices to accomplish a shared goal: locating a lost submarine before a dangerous situation spirals into open conflict. The stakes feel immediate, and the only way forward is genuine collaboration.

What makes this game stand apart from typical puzzle titles is its asymmetric design philosophy. Each player is given a completely different set of information, controls, and responsibilities. One person may be managing systems or reading data that the other cannot see at all, while their partner handles an entirely separate side of the same problem. Neither player has the full picture on their own, which means constant communication is not just encouraged but absolutely required. You cannot brute-force your way through the puzzles alone, no matter how experienced you are.

The companion app itself is one half of the full experience. To play, you need the main game, which is available on console and PC platforms. The companion app runs alongside it on a second device, giving the second player their own interface and role within the shared mission. This setup creates a genuinely immersive split experience where both players feel equally invested and equally necessary.

As you progress through the submarine scenario, the puzzles become increasingly layered and complex. Early stages introduce you to the communication rhythm required between both players, while later challenges demand faster thinking, more precise coordination, and a stronger grasp of how your respective roles intersect. The difficulty curve is intentional and well-paced, rewarding teams that develop a good working dynamic.

Key aspects of the How 2 Escape: Lost Submarine experience include:

A fully cooperative two-player structure where solo play is not possible by design
Asymmetric roles that give each player unique responsibilities and information
A progressive puzzle system that scales in complexity as the mission advances
A companion app format that pairs with the main console or PC game
A narrative framing centered on preventing conflict aboard a lost submarine

Running the companion app through MuMuPlayer on PC gives players a comfortable and stable platform for managing their side of the mission. The larger screen real estate makes it easier to read information clearly, and the reliable performance means you stay focused on coordination rather than troubleshooting your device. Whether you are the one running the companion app or supporting your partner through a session, MuMuPlayer keeps the experience smooth from start to finish.
