Welcome to Silent Depth, the first real 3d submarine simulation for mobile devices. Being a member of the Silent Service of the US Navy you take command of a Gato/Balao class submarine and go on extended patrols in the dangerous waters of the Pacific in world war II. Your task is to attack Japanese merchant ships without being caught by destroyer escorts either using your torpedo weapons or your deck gun in a realistic environment. Control your submarine, use your strengths and find the weak spots of your enemy. Only that way you have a chance to survive this thrilling 3d simulation. Run silent, run deep!

No ads, no in-app purchases, just the full game for one price. Free updates for the life time - and there will be much more content to come! Attacking war planes, medals, achievements, missions to name a few.

This is the first non arcade submarine simulation game for mobile devices playing in the Pacific Ocean.

* Real day/night cycles with realistic sun/moon/star settings and lighting
* Different weather conditions with changed visibility (including fog, rain)
* Realistic water
* A huge world: The whole Pacific!
* Realistic damage models, repair your submarine, prioritize your tasks dependent whether your submarine is surfaced or not
* Sink enemy ships with torpedoes or your deck gun
* More than 10 different ships to encounter like battleships, carriers, destroyers, cruisers, tankers, troop transporters, freighters, submarines
* Different kind of fleets, single targets, with and without escorts are being generated

What is there is awesome. The graphics are good and it is fun to play but you always want more. 1) No medals, it has a place for medals but never have seen one. 2) I was led to believe there would be two classes of subs and more variety of enemy ships. 3) except for home base there are no graphics for islands or ports. Silent hunter 1 (the only good one) had opportunity to infiltrate enemy ports. 4) no specific missions 5) Silent Hunter 1 had a "ward room" or something where you could go in anytime and check your log book and keep track of progress and past missions.

I would recommend an update that has been promised but never came.


Improve combat effects

This is a very high quality & realistic sub sim in my opinion. Everything from the physics to details is impressive as are the 3D views.

A big area for improvement in my opinion is combat effects. It would be nice to hear sonar pings from enemy ships, for your crew members voice to sound more urgent when getting depth charged, sound effects for enemy ships that you can hear while surfaced (for example if your spotted a loudspeaker will tell sailors in Japanese to go to battle stations) and sound effects for depth charges hitting the water and exploding at various depths.

I know some people have mentioned in game tutorials. Yes this is an area that could be improved. However, there is a Silent Depth Manual (google it) that will teach you all the basics. It’s a good manual complete with decent explanations and pictures.

Five stars well deserved, keep up the great work.

Needs specific missions

Would be good to add missions like search and destroy where one has to do recon to identify and sink certain vessels (if discernible) or interdict certain convoys at a probable location.

Also, and this is critical, we should be able to see the torpedo load/ready state on the ship info/damage page as well. Unless I'm missing something I can only get that info currently if I'm at periscope depth. Strategically, there are battles where I don't want to raise the scope UNTIL the torpedoes are re-loaded and ready to fire.
