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.

What a great escape game!!!! A bit different from the first opus! If you like to solve riddles, this game is for you!
This game got really hard near the end. Definitely harder than some others in the series. But we enjoyed. Definitely almost sparked some arguments. I carried the team.
Some very fun puzzles!
It's a great co-op puzzle game. Most of the gameplay is still communicating symbols and scenes by caption-explaining things, but it's a great experience for two, bite-sized for one session, and well-paced. I am really looking forward to the next game in the series! Might be a bit short for its price, but hey you buy once for two players' fun!
I mean... It's alright? I'd give it a neutral rating. If you like escape room games, you'll be alright with this game, though I'm not a huge fan of the asymmetrical aspect on this one... I can almost say I hate making player 2 use a phone/tablet. If that was an optional way of playing it, while you could play it on PC too, wicked. Huge 'do you guys not have phones?' moment. Might as well print it out as an interactive book, no? Perhaps it would be a little more lackluster if you played the glorified PDF on PC.. who knows. 'Cross-platform plays on two devices' is a weird way of saying 'this offline game requires you to have someone willing to download a phone app just so they can guide you through the game via the interactive manual we decided to make only available on phones'. The one and only upside to this I see is that you only need a single computer, anyone coming over for example, can get the phone app and you're good to go. Anyway... You go around solving rooms of puzzles. The puzzles themselves are fine. I really liked the way they implemented the hint machine. You have to collect cards in order to be able to get a code for any of the room's puzzles. Then you need to give the code to your partner who actually gets the hint. The cards are not hard to find at all, but it's more involved than just pressing a hint button at least. I couldn't tell you anything about the story, there were cutscenes and everything, but I skipped them all. All the 'wait for your partner' screens can be ignored (I think?). It's an offline game.. you just type a code into your disguised and strangely indexed manual (companion app), and you'll both end up in the same place anyway.
After trying all of the combos of latitude, longitude, and oxygen provided on the app and getting absolutely nowhere I figured I'd use the hint machine. It provides no hints. I do not have the patience for this. I'd only recommend this to people that enjoyed the first game, and are willing to have patience to get this to do whatever it is that it is supposed to do.
Every time I try to enter the first clue, the app freezes and I can't proceed. Please do something about this.
This is a cooperative puzzle game that combines elements of an adventure game and intellectual tasks. If you are looking for a game like this, I recommend it!
