## What is Submarine Simulator?

Take command of a German U-boat in World War II. Hunt enemy convoys, line up the perfect torpedo shot and slip away before the destroyers find you — a realistic 3D submarine simulator built for players who like to think before they fire.

【HOW A U-BOAT ATTACK WORKS】
1. Find the convoy — listen with the hydrophone (sonar) and watch the tactical map
2. Close in at periscope depth without being spotted
3. Observe the target through the periscope: bearing, range, speed and angle on the bow
4. Enter the data into the T.D.C. (Torpedo Data Computer) — it works out the gyro angle
5. Fire your torpedoes, then dive deep and evade the depth charges

【FEATURES】
・Campaign of 5 missions, from your first war patrol to a full convoy battle
・Realistic U-boat controls: engine telegraph, depth, course and battery
・Periscope, hydrophone and lookouts to detect and track warships and merchant ships
・Torpedo attacks with the T.D.C., just like real WW2 submarine commanders
・Escort destroyers that hunt you with sonar and depth charges
・Tactical map with contacts, predicted courses and range rings
・Time acceleration, auto-save and continue
・Graphics adjust automatically to your device
・Single-player naval warfare — no PvP, play at your own pace
・Available in 17 languages

Whether you love WW2 history, naval warfare and warships, or classic submarine games, this U-boat simulator puts you in the captain's seat. Can you sink the convoy and bring your crew home?

### 1/5 — In Japanese

*2026-01-01*

Was able to download but then you can’t get anywhere as the language isn’t in English and then the boat doesn’t even generate. Good potential also to many ads

### 1/5 — Different language

*2025-12-19*

The language was in Japanese and I couldn’t even see the sun much less any ships to sink.

### 1/5 — Terrible waste

*2025-05-25*

Can’t read font. Bad color selection and just immature design.

### 3/5 — Too many adds, period.

*2025-05-23*

Great little game. Would love to keep it, but just too many adds. Uninstalled.

### 1/5 — Lost potential

*2025-01-10*

The manual is horrible, nothing on how to aim torpedos , maybe if you already know how to set gyro angles on ww 2 torpedos you will know how to set the, up to send them off. I tried guessing, it didn’t go well, I figured out how to steer the boat more or less. Can’t find anything on using the fish though and I’m not up to date on sending them to hit moving ships from a moving boat. I was excited to download , I thought I found a sim exactly like I wanted , so sad. Disappointed and not worth wasting time on without being able to use torpedoes.

### 1/5 — Boring

*2024-03-26*

There’s nothing to do

### 5/5 — One of the best

*2023-07-15*

This is a really good game, but I will say that it needs sounds and that it can have the option to have English writing in the periscope
