About this game

U-Boat Simulator (Demo) is the free test version of the full game U-Boat Simulator.
In this game set in World War 2, you can control a U-Boat VII-C German submarine, search enemy ships and engage in dangerous battles to sink them with torpedoes.
This is not an “arcade” game but a complex and realistic simulator, a bit difficult at the beginning but after a little practice you will enjoy hours and hours of fun.
It has options that you can enable to make the game more realistic and difficult, you can look around your submarine with the 3D views, and so on…

In this web site you will find the instructions for this game, several screenshots and a forum where you can post comments, ideas, report bugs, ask for help or add your stories and screenshots.

Here is a brief explanation:

You can scroll and zoom the map with your fingers, and its limitations are highlighted by yellow lines on the edges.
Your submarine is green, enemies are red, allies are blue and neutral units are black, while the units not yet identified are gray.
The submarine is indicated with a diamond and a cross, warships with a diamond and commercial vessels with a square.

On the top left of the screen there are the indicators with the speed, course and depth.
Clicking on it opens a window to edit them and MOVE THE SUBMARINE.

Always at the top, there are the boxes with the health, the batteries, the oxygen and fuel, the date and time acceleration.
Clicking on the box acceleration is possible to increase the speed of the game.

On the bottom and left there is the map scale.

On the bottom of the screen there are buttons to go on the map, to go to the screen of the charging torpedoes, to bring up the window for launching torpedoes and guidelines, the button to exit the game and on the right the button to put in pause the game.

Clicking on any unit, on the left some usefull informations will appear about its distance, course, speed etc..

The fuel is consumed only browsing on the surface, the batteries and the oxygen staying underwater (they can be recharged at the surface), health decreases when you bang against a ship, when hit by the guns of the enemy ships or near breaks out of depth charges.

This is the free demo version of the game, it contains some limitations, it is better to download it just to have an idea of the game and to test if this game is compatible with your smartphone.

Whoever the designer is. It is a game, not a complex and utterly frustrating puzzle to solve. If I want o e of these, I will go back to a real world. Really, dude, something simpler and more entertaining,game-like would do. As is it is ridiculous to play. Who has time to read the lengthy manual. What a stupid idea. Gone forever from my device.

This game is fairly good in my opinion, but for a demo, i dont think that buying the full version actually have any difference, except of course, reloading the sub. Buying the full version feels like paying 10 dollars for an ad blocker. Overall, very nice game, could be fixed

Absolutely garbage there's no tutorial. And from what I heard you have to go online to get a tutorial. How fkn hard is it to add it to the game. Or even AR least have little pop-ups that tells you what each function does. This game could be great if it had a creator that knew what he was doing
