How 2 Escape: Lost Submarine, the next entry in the immersive co-op puzzle franchise, is launching on June 24. This unique two-person adventure blends escape room mechanics with high-stakes storytelling, challenging players to cooperate across devices to prevent the outbreak of a global war.

Building on the clever asymmetrical gameplay of its predecessor, Lost Submarine raises the bar for cooperative problem-solving. One player explores a mysterious submarine from the inside, navigating corridors, interacting with mechanisms, and uncovering clues. Meanwhile, their partner provides critical intel and puzzle solutions through the free How 2 Escape: Lost Submarine Companion App, available on PC, iOS, and Android.
Only by working together—communicating clearly and thinking fast—can players crack the codes and alter the course of history.
A Crisis Beneath the Surface
Set against a tense backdrop of geopolitical brinkmanship, Lost Submarine places players in a chilling scenario. After a critical military base falls into enemy hands, the government issues a strike order. But following last-minute diplomacy, the torpedo launch is called off. There’s just one problem: the submarine carrying the payload, The Triumphant, is deep underwater and unreachable.

Enter Haurée and Leroy—two elite naval strategists tasked with getting the message through. As players step into their roles, they’ll face twisted moral dilemmas, fractured crew loyalty, and a race against time where every puzzle solved might mean the difference between peace and annihilation.
