Submarine Simulator vs Competitive Tennis Challenge

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.
