A tactical WWII submarine sim demo focused on chart-based attacks: track ships by hydrophone and periscope, plot an intercept, estimate range, set up the Torpedo Data Computer, fire torpedoes, and evade escorts through tutorials, standalone encounters, and a limited scenario generator.

About This DemoThe Silent Shark demo is a focused slice of the tactical submarine attack gameplay: tracking contacts, plotting an approach, estimating range, setting up the TDC, firing torpedoes, and escaping before escorts pin you down.You command from the chart and instruments rather than an arcade cockpit. Use hydrophone bearings, periscope observations, ship identification, the stadimeter, map tools, depth and speed orders, and torpedo tube controls to build a firing solution from incomplete information.Included in the Demo- Basic and advanced tutorials covering chart work, periscope use, hydrophone tracking, stadimeter range estimation, TDC setup, and torpedo attacks.- Four standalone encounter scenarios, from a simple single-ship attack to harder convoy encounters in rain and darkness.- A limited scenario generator for small custom encounters with weather, time of day, distance, heading, and enemy ship settings.- Core submarine instruments and attack workflow: engine telegraph, depth control, periscope, hydrophone, stadimeter, TDC, torpedo tubes, gyro angle, spread, and salvo control.- Destroyer escorts that can search, predict, and respond if your attack gives you away.Not Included in the DemoThe full Pacific campaign is not included in this demo. Campaign patrol zones, long-range mission planning, radio intelligence, submarine progression, campaign resources, base operations, and the full scenario editor are part of the full game.If you enjoy the demo, please wishlist Silent Shark on Steam to follow development and the full release.

Silent Shark Demo

A tactical, map-based WWII submarine sim set in the Pacific Theater: Approach, intercept, strike unseen, withdraw into the deep. With realistic instruments, a Torpedo Data Computer (TDC), and including a full campaign with missions, patrol zones, radio intel, and more.

Silent Shark is a tactical and realism-focused WWII submarine simulator built around plotting, estimation, and submarine command, set in the Pacific Theater.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras/34faa454d7fe8f2b8c08cd29b26a8179.poster.avif?t=1782731312" width=1170 height=658 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras/34faa454d7fe8f2b8c08cd29b26a8179.webm?t=1782731312" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras/34faa454d7fe8f2b8c08cd29b26a8179.mp4?t=1782731312" type="video/mp4"></video>Track contacts by hydrophone, work out their course and speed, identify ships through the periscope, estimate range with a stadimeter, and build your firing solution from imperfect information. The game is played on a tactical chart with period-inspired instruments and deliberate controls.A good attack takes preparation. You need to approach from the right angle, manage depth and speed, account for visibility and sea state, set up the torpedoes, and leave yourself a way out before escorts respond.If destroyers do locate you, be prepared for evasive maneuvers and paying attention when to go hard and fast, or slow and silent.<h2 class="bb_tag" >Core Features</h2><ul class="bb_ul"><li>Map tools like compass, ruler, timestamped points, and angles help you to hunt for the perfect course to intercept.</li></ul><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras/d322906d0f61dcaa0fa86043b8a0a4f9.avif?t=1782731312" data-big-src=https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras_big/d322906d0f61dcaa0fa86043b8a0a4f9.avif?t=1782731312 width=1560 height=942 /><ul class="bb_ul"><li>Realistic replicas of historical instruments such as the engine telegraph, depth meter, and stopwatch.</li><li>Periscope with 1.5x and 6x zoom shows a stylized 3D view of contacts within visibility range.</li><li>Hydrophone for tracking ships and convoys by sound - tell the difference between freighters and escort by pitch.</li></ul><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras/73aebe8a6127fa21a489594ab8edf7db.avif?t=1782731312" data-big-src=https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras_big/73aebe8a6127fa21a489594ab8edf7db.avif?t=1782731312 width=1560 height=942 /><ul class="bb_ul"><li>Manual range estimation of ships with a fully functional stadimeter: identify the ship to get its mast height, then auto-calculate the distance by observing the angle to the top of the mast.</li><li>Torpedo Data Computer (TDC) with a Position Keeper: Enter angle-on-bow, target speed, target bearing, and target distance to fire torpedoes that will hit their targets.</li><li>Torpedo tube flooding, gyro angle, spread, and salvo control with a torpedo firing box modeled after the real thing.</li><li>Sea state, weather, time-of-day, all have a significant effect on visibility and stealth<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras/34eb4d976691663a8e3ef6fc78dac136.avif?t=1782731312" data-big-src=https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4705650/extras_big/34eb4d976691663a8e3ef6fc78dac136.avif?t=1782731312 width=1560 height=956 /></li><li>Dynamic thermal layers based on time of day and region, measured by bathythermographic readings</li><li>Destroyer escorts, aircraft, merchant traffic, and convoy encounters.

John is the creator of the head tracking app SmoothTrack and the thought organizing app Mindscope. He thinks it's a bit strange to talk about himself in the third person, but doesn't really know how else to write this section.He grew up playing the sub sim Silent Service II on Atari, then later discovered Silent Hunter IV, and more recently, UBoat - he then decided to take the parts he loved most about these games - the map mode - and double down on that and turn it into the sub sim of his own dreams.
