How co-op works
Asymmetric two-player co-op across two devices. One player investigates and interacts inside the missing submarine; the partner uses a free companion app to gather complementary information, so both must compare clues and coordinate increasingly difficult puzzle solutions.
About this game
How 2 Escape: Lost Submarine is an asymmetric co-op puzzle adventure built for two players working from separate screens. One player uses the full PC version while their partner connects through a free companion app on mobile or another device. Together you must reach a stranded submarine and stop an international crisis, each seeing different information and controls that force constant teamwork.

The game centers on communication-heavy puzzle solving where neither player has the full picture alone. You will coordinate dials, switches, maps, and clues across your two screens, piecing together solutions that demand back-and-forth dialogue. The puzzles grow in complexity as you progress, rewarding pairs who can share details clearly and think through problems together.
Online cross-platform co-op is the only mode, designed for voice chat sessions with a trusted friend. The asymmetric setup and steady difficulty curve make it ideal for partners who enjoy escape room-style challenges and want a shared story to tackle over multiple sessions.

Frequently Asked Questions
Does my friend need to buy the game too?
No, only one player needs to purchase the full game on Steam. The second player downloads a free companion app on their mobile device or another platform and joins through that.
Can we play this using matchmaking with strangers?
This game is designed for you and a specific friend playing together with voice chat. It's not built for matchmaking with random players-the communication-heavy puzzles really need coordination with someone you know.
What makes this asymmetric co-op?
Each player sees different information and controls on their own screen. Neither of you gets the full picture alone, so you have to constantly talk and share what you're seeing to solve the puzzles together.
Can we play this in a single session or is it meant to be played over multiple days?
The puzzles grow more complex as you progress, and the game is designed as a shared story experience. While you could marathon it, the steady difficulty curve makes it well-suited for tackling over several sessions with your co-op partner.
