Crush Depth

This appears to be the first genuine attempt to properly simulate the true workings of a German U-boat of WW2. This is not based on an impression but on actual blue prints and meticulous research carried out by a dedicated and knowledgeable team of enthusiasts. On entering the main menu screen I chose the Museum as my first port of call. It was here that it struck me that this could become something special. I had expected to find simple pictures and short scripts of information on the subject, instead I found a working engine and equipment modelled with painstaking detail. Whole videos were displayed on the museum walls just as you might expect in a true maritime museum. There was even a video on the games development showing that the developers of this simulator really wish to keep you involved with their progress. That was when I felt my money was well spent in helping this project to continue. Enthused by my Museum experience I went on to try out the Sandbox menu option. It is clear that the player is limited in what can be done as this is a simulation which is very much in its infancy. You should not expect anything close to a fully functioning title at this stage which the developers have made very clear. Even so, what I was able to do I found extremely satisfying. The interior of the U-boat is incredible. So many dials, switches and wheels to turn. This is an attempt at making as much of what you can see actually functional. Its not all just for show, most of what you see will eventually serve a purpose and its that thought which makes this project so exciting. Even discovering the radio was a joy, having to turn it on correctly, find channels and tune it felt rewarding. Which brings me to a subject I feel can make or break the submarine genre 'Sound quality'. If there were ever a subject that needs to fill you with immersion its capturing the feeling of being on or under the ocean. Add to that the sounds and feelings of being on board a U-boat during war time and it should feel intense. So far the sound quality in this simulation is wonderful. The engines rumble and roar at full speed, the doors shut and open with a weighty clunk. There's an ambience when under water which you don't just hear but you feel.
So to conclude, I sincerely hope that this title and its developers receive all the backing they can get. This is an ambitious project and an opportunity to see what we would all wish for in a submarine simulation become a reality. No doubt it may take time to complete and there may be hiccups along the way. But if the vision of these developers can be achieved its something well worth investing in.
Good Luck Devs and Thank you

Deutsches Review -> weiter unten :)
First impressions
The things done so far and the effort until now are really impressive. This might become the most detailed technical subsim of all times. Sadly there are some "buts". You shouldnt forget, "playable" is nothing. Its not a game, its a tech demo. And even the usable parts in the tech demo are only at around 30% finished currently. You have seen (in the very well made museum) and tried everything usable in the boat quite fast. So, the fun is more or less just in the first moments, when you are totally impressed by the functional devices. Awesome work. But this doesnt last long. All this, combined with a kind of promise for a full game maybe at some point in the future, at a price of AAA (50 bucks) is hard to explain. I was lucky and got this game as a gift :) And yes, i know about all the progress, which is not really visible. This is considered in this review :)
Conclusion
The TechDemo is quite neat and a unique experience. I see the value under the surface of this unfinished thing. Using a Diesel or the electric engines like the real ones is something you would never expect to be possible until this game showed up. Also the museum is very nicely done. If the devs keep this up, this might be the coolest technical simulation of a german type VII boat that you have seen. But its not much fun at the moment - its more about supporting the development.
As a sidenote, why i was unsure how to rate this product. I was contacted by the devs to participate in the development. And what followed then was a bit strange ;)
So anyway, i was not sure if i should recommend it. But i want to show my support. Thumbs up. I hope you keep the effort, the communication and the visible progress at that level ;) great work so far!
What do you think about the Demo and the upcoming game?

Erster Eindruck
Schwierig, was soll man sagen. Ich bin etwas hin- und her gerissen. Erstmal das Positive: Es ist schon beeindruckend, was man bisher so sieht! Die technische Detailtiefe (die Diesel und E-Motoren sind 1:1 simuliert und funktionsfähig!) und die Qualität der 3D-Modelle ist herausragend, das hat es noch nicht gegeben. Wirklich einmalige Arbeit! Das muss man tatsächlich mal erlebt haben. Man kommt allerdings doch recht schnell zum Unschönen. Irgendwie ist plötzlich alles gesehen, gerade als es anfängt Spaß zu machen. Die TechDemo ist nicht so umfangreich, wie man es vielleicht erwartet. Man hat schnell alles ausprobiert. Momentan ist selbst die Demo gefühlt nicht mal zur Hälfte fertig. Und es ist weit davon entfernt, ein Spiel zu sein. Zudem bewerte ich hier nicht die Grafik oder Ähnliches. Doch dafür und das Versprechen, dass man irgendwann vielleicht ein fertiges und zugegeben, einzigartiges Produkt bekommt, sind 50 Euro doch schon ziemlich happig. Aber ich habe es als Geschenk bekommen. Auch deswegen hebe ich den Daumen. Aber auch, um meinen Support zu zeigen. Sowas hat noch niemand versucht.
Wäre wirklich toll, wenn es klappt :) Was denkt ihr über die Demo/das Spiel??

This has the potential to be the most Realistic SubSim Ever produced with Blueprint level of Simulation, the like of which have never before seen.
Accurately manage electrical systems and Diesel engines in real-time with a stunning level of accuracy throughout.
My FIRST Hour Experience
Video Transcript
OK, I discovered this title today 11th Feb 2020 & I have never heard about it before hand & knew absolutely nothing.
What I have learnt is that this is a hardcore Submarine Simulation in VERY Early Access....and I will now explain exactly what that means if you buy access today (11th Feb 2020); you will be investing in the development of this project and must understand that this is nowhere near ready to play....yet.
FIRST 10mins was Really bad. Nothing would load (had some kind of authentication failure with the server) I tried to create a character which just got me stuck and there were some very odd clothing options to say the very least. In short it was not going well & I really thought this was some kind of ploy, scam fake game (spoiler alert: It is none of these things).
FIRST 20mins I hard closed the game multiple times, tried to load museum & sandbox...nothing was working & I was already formulating a poor review perspective in my head, then (for whatever reason) after 3/4 reload attempts the bottom left Authentication error change and things appeared to be working so I opened the sandbox option & got a Disconnect error (something about client failed to bootstrap). So I hard reloaded the game again 5th time and tried again, this time the loading screen stayed present for 5minutes...so I hard reloaded probably for the last time....
FIRST 30minsFINALLY something loaded. I was clearly on top of a sub. It immediately reminded me of Silent Hunter and I could see that there were many placeholders and detail, whilst present was indeed limited. I opened the hatch and climbed down (again reminiscent of SH).
The control room was inaccessible but I could see some depth and steering mechanisms, I proceeded towards the rear of the ship and the first thing that impressed me was the audio as i opened each hatch...a very nice immersive detail.
I continued through the sleeping quarters, the galley, the diesel engine rooms and into the electric and rear torpedo areas. I was mildly impressed, I could see some potential in the modelling etc.. but I wasn’t really feeling like my £36 was at this point a good investment choice, however I cannot review what I don’t understand so I continued investigating the ship and its contents some more.
I found many interactive elements, from pressure gauges, dials & levers and it quickly became apparent to me that this was incredibly accurate, like blueprints recreation accurate and I became considerably more intrigued. I proceeded to move away from the electric controls which I had no knowledge of and decided to investigate back towards the bow, first through to the engine room where I fiddled and tweaked a little bit then I continued on to discover more accurately recreated interactive elements like cupboards, lockers and even a john. The galley had some inactive water taps, labelled tap or drinking water. It was clear that whilst some physics elements were very real like closing a door whilst in the way would push you with it (I liked that) but you could interact with some of the lockers through the walls (obviously a work in progress). I was pretty impressed to see almost every single hidden storage location was interactive, & I hope one day to be able to put things in them.
I returned to the controls and attempted to dive, having not closed the hatch on the way in I was curious to see what would happen if I could dive, and we could dive. Not far, as we were stationed in a UBoat dock but enough for me to climb up and witness the submersion. Sadly water did not pour in, but I was impressed to discover that I could not only leave the boat but swim around…this is certainly something that potentially offers extreme levels of realism for the future. Sadly I could find no way to dive down back to the boat, or climb out to investigate what appeared to be a primitive Helicopter; so instead I opted to hard reset once again and loaded the museum and this is where things eventually got very interesting indeed.
1 Hour + The museum was actually quite interesting, I saw a floating sniper at first (that’s not important) there was quite a bit of information on the walls, models, videos and info about AA Deck guns … torpedoes and depth charges & even a full scale submarine to explore; although incomplete.
I wandered around looking at the Radio equipment & enigma machines and then finally whilst formulating a rather dismal yet hopeful review narrative in my head I stumbled across the diesel engine. It was the same as the one in the sub, but this time I managed to start it; somewhat by accident or luck.
I suddenly realised what this sim was, it’s a proper simulator, the real deal the type of simulator I have wanted to experience nearly my entire life..I quickly returned to the sub and attempted to recreate what I had just achieved, it took a while…all you need to do is increase the throttle and it will start, but I spent a good few minutes twiddling things, opening and closing this and that before I figured out how simple it was to start and then we were actually driving the sub…moving through the water out of the pen and into open sea.
For the first time I saw the subs outer shell and then I spotted a ship. An enemy ship, I thought I could try and sink it but I couldn’t remember how to fire the torpedo (there was a button) so I started button mashing and threw my guts up all of the tower, immediately the john made more sense. I started opening controls I didn’t know existed and spawned other ships in, then I started tweaking the weather & FISHING North Atlantic THIS is how you do waves and bad weather….OK so at this point the FPS had sprung a leak and attempted to plug it with a live hand grenade which immediately went off and dropped the FPS so low I couldn’t turn my view…but it didn’t matter at all because the audio was totally immersive, the waves were actually scary as hell and I felt like I was at war…then I stumbled across the manual steering controls and started to dive leaving me floating on the surface of the ocean in a storm and accepting my inevitable fate…I’ve just invested £36 pounds in the most amazing Submarine Simulator and I sure as hell wont be requesting a refund…this has to be made, this has to have solid FPS and I have to be a part of this development somehow.
I am totally hooked. Scared that this might never reach its full potential, but at the same time I feel responsible to try and make it happen. If you are a hardcore sim fan & have the available funds there really is every reason to try and get behind this development….it is the best simulation experience I have ever had….oh and the torpedoes work too; but I couldn't figure out how??

Crush Depth is an extremely in-depth simulator, with a lot of promise. Think DCS World, but for WW2 German Submarines. It's well done, with great graphics, and great performance given the level of simulation. That being said, this is an extremely early release, and is nowhere near complete.

I just wanted to take a minute and tell you my thoughts on the game so far. I just had the chance to check out the museum and it was by far the most mindblowing video game expieriance I have ever seen. The attention to detail is quite frankly astounding! Especially for part time developers such as yourselves. I love how you are taking your time and making sure you do things right before moving on to the next system. The fact that you guys are paying such close attention to small subsystems such as the Enigma machine is mind blowing to me as they are so advanced and I would assume equally hard to code. Especially since they are not core game components. I love the fact that you guys are keeping the community up to date on all you do as well. Most developers just treat the community as a source of money and only change something when the whole community has to lash out. Not these guys they are constantly talking with individual players about their concerns and ideas. (in the Discord) I think my favourite part of the whole museum was the books/research section. The amount of resources collected by you guys and the community took me aback as I know from experiance they are not easy to find. This however while amazing brings me to one of my biggest concerns for the game. The fact that this game is so complex definetly is a force to reckon with against new players. Most of which whom are not engineers or historians. These jobs took months of training just to learn one position and the fact that you guys are implementing a 1 to 1 scale model into the game concerns me that players will not want to read through multiple manuals just to learn one position or system on the ship. The use of active engagement tutorials is certainly a way to remedy this however! The game in it's current state is in no position to be considered a playable state. It is essentially just a place for the devs to show their progress in making the game. Please keep up all your hard work! This game is the first of it's kind and is opening the door to hyper realistic simulation. I would rate 10/10 this is definetly the most educated development community I have ever seen in any video game. If you want to learn a ton about the German side of ww2 and have fun doing it this game is for you.

Still in a early state as advertised but already pretty cool. Has me sitting on the edge of my seat for new updates :)

I sincerely hope this comes together. It has the potential now to be the finest Type 7 simulation. The current engine room is excellent and I do believe they even have the firing order correct on the diesel!! Attention to detail like that gives big hope for a one of a kind simulation!! Really Hopeful!!
