About How 2 Escape: Lost Submarine

The unique co-op experience that made How 2 Escape a success is back with improved gameplay and new challenging puzzles!

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.

SAVE THE WORLD

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.

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 !

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.

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!

It's *okay*, but the puzzles are pretty much all just annoying "communicate this unclear information to your partner, but also it's not clear what information you need to communicate" - like Keep Talking and Nobody Explodes but without the guardrails that establish the rules you're going to be working with first, which makes it worse. And because the bulk of the puzzle is not figuring out problems, but figuring out *what the problem is*, it's not replayable - you *could* escalate the difficulty but it would just be like "now count 12 things" instead of "now count 6 things", or "now read 12 numbers off your screen and wait for your partner to find them on their screen" instead of doing that with 6 numbers. A few of the puzzles worked as both puzzle and communication thing (the vent-maze was a good one in that it was relatively clear what you were doing, but then introduced surprises in the maze). I appreciate that you only have to buy one copy for two players, but then that also becomes an issue when the "not in the submarine" player is stuck mostly reading manuals (again, the vent-maze being a pleasant exception). My wife, who does not enjoy reading game manuals, was stuck in…

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 …
