Drive the German U-Boat submarine in the most realistic submarine simulator and sink enemy ships! Experience commanding a World War II U-Boat and engage in unrestricted submarine operations.

🎮 Game Overview

Track down massive tanker ships carrying vital supplies and the destroyers escorting them. Use torpedoes to sink your targets while staying hidden beneath the waves.

Utilize a hydrophone (underwater microphone) to detect enemy positions without being discovered. Estimate the best torpedo firing point based on enemy speed and course.

If detected, tankers will begin evasive zigzag maneuvers while destroyers charge straight at you, dropping depth charges. Dive deep to escape their sonar and wait for the danger to pass. Once you evade pursuit, line up the perfect shot and strike back with your torpedoes.

✨ Features

• Easy-to-understand yet realistic submarine control panel
• Speedy gameplay with time acceleration function
• High quality 3D models and realistic graphics
• Torpedo firing system based on a realistic Torpedo Data Computer (T.D.C)
• Auto-save system that allows continuous play

🛠️ Support the Future of This Game

This project is currently being upgraded and will be fully rebuilt in Unity to improve graphics, performance, and extensibility. Your donations will directly support the following:

• Unity engine migration for higher quality visuals and smoother controls
• Online multiplayer development (co-op & PvP submarine combat)
• Server costs and Unity assets required for new features

Every contribution helps accelerate development and brings new features closer to release. Thank you for supporting the evolution of this submarine simulator!

📘 How to Play

Select a difficulty level on the title screen and tap the Start button.

At the beginning of the mission, dive to periscope depth and use the Hydrophone to locate enemy ships. Once you identify the bearing of the enemy fleet, surface and move closer.

Approach to a safe distance, then dive again to periscope depth to avoid detection and prepare for attack.

🔧 T.D.C (Torpedo Data Computer) Settings

When the target is within torpedo range (5 km), switch to the periscope view and accurately input the following parameters:

• Target Bearing: Direction from your submarine to the target. Linked with periscope direction and set automatically.
• Target Speed: Estimate by observing the enemy ship’s movement through the periscope.
• Target Distance: Check the distance between your sub and the enemy vessel.
• Target Angle on Bow: The angle at which you see the enemy ship’s hull. Use periscope zoom for accuracy.

After entering all parameters, the torpedo gyro angle is calculated automatically. Double-check your settings and tap the Fire button to launch the torpedo.

🏁 Mission Clear

Sink the required tonnage based on your chosen difficulty level to complete the mission. When an enemy ship is sunk, the remaining tonnage needed will be shown in the upper-left message panel.
