About

The latest edition in the How 2 Escape series, How 2 Escape: Lost Submarine has you and a partner work together to locate a missing submarine and prevent the start of a global war.
An important allied military base has been captured by enemy forces, prompting the government to preemptively order the launch of a torpedo to reclaim it - despite the potential for countless allied deaths.
However, after further internal discussions and negotiations with the enemy, the government cancelled the strike that could spark a potential global war. The only problem is "The Triumphant," the submarine carrying the torpedo, is out of communication range and no one can confirm if the cancellation orders have reached the submarine.
To prevent war, the government has tasked its two best experts, Haurée and Leroy, two strategic masterminds of the submarine fleet, to locate “The Triumphant” before time runs out and spread the latest information. These experts will face a reality they did not expect. Underwater, the startling torpedo decision broke out, igniting a moral dilemma among the sailors.
Put your communication and puzzle-solving skills to the test as you and a partner work together to prevent the start of war! Each of you has a crucial role to play that requires logic, coordination, observation and, above all, communication!
As player one, your job is to locate and investigate the inside of the submarine, where you’ll explore and interact with the environment.
Your friend is tasked with using the dedicated free companion app* to gather additional information so you both can solve the puzzles together.

Played after the first of the series with my gf and yes, it's a lot of fun, misunderstandings and trying to figure out what the other is seeing. The art style is still really clean and the riddles well executed. However, it is easier than the first one and is, like others said, pretty straight forward. We still loved playing a few hours together ! Great game for either couples, friends, relatives, etc !
COOL
Игра не плохая, но вот разработчики конечно выпускают английскую версию, но при этом, используют сложные слова и предложения. А не доступное описание, лёгким языком. Из-за этого считай, геймдизайн и QA очень плохо справился со своей задачей/работой.
we need cloud save, Ach have cn too. 我们需要云存档,成就也需要中文。 游戏质量可以,可以推荐。 202512,steam,steam掉卡掉物抵扣,它处自定义包入的本体约9元。 爱人如己,目前就这,看以后追评。
Honestly I didn't like this one as much as the first How 2 Escape, it wasn't bad but it just really didn't compare for me. None of the puzzles were really memorable to me yet I can remember a good majority of the puzzles from the first How 2 Escape. That doesn't warrant a thumbs down though, overall every puzzle was still pretty solid, except for the language decoder one. I can not say me or my friend enjoyed that one very much at all. If you're looking for a two player puzzle game, it's pretty solid, I'd wait for it to be on sale though.
比起同系列火车 更加偏向加强了游戏画面和细节 谜题相对简单 ♥♥♥♥
是值得推荐的双人游戏,谜题有一定的思考空间又不会过难
可玩性非常的高,和朋友玩很有趣,是一款非常不错的双人解谜游戏,建议大家都来玩。
Very nice . recommended
What a great escape game!!!! A bit different from the first opus! If you like to solve riddles, this game is for you!
