Hunt enemy submarines in three dimensions. Deploy depth charges, fire torpedoes, ping with sonar - and sink them before they sink you. The classic guessing game has gone three-dimensional. In Submersible, enemy subs hide across width, length, AND depth — turning every shot into a calculated risk and every match into a tactical hunt. Your mission: locate the enemy fleet and destroy it before they destroy yours. • THREE WEAPONS Depth charges for area damage. Torpedoes for straight-line strikes. Sonar to reveal entire depth layers. Each turn is a choice between aggression and intel — and detection is not destruction. • HUNT IN 3D Rotate the tactical grid. Zoom into any depth layer. Track enemy contacts across a fully three-dimensional battlefield. • DAILY OPERATIONS A new tactical challenge every day. Six rotating variants — from Piranha Party (all small subs, all fast) to Standoff (the only daily where you're trying to miss). Climb the global leaderboards and protect your streak. • THREE DIFFICULTIES Easy, Normal, and Hard AI. The fleet is the same. The hunter is not. • MULTIPLAYER VIA GAME CENTER Real-time matches against friends or random opponents. Same rules. Same depths. Different commander on the other side. • ACHIEVEMENTS & LEADERBOARDS Twenty-four achievements to unlock. Track your accuracy, your streaks, your fleet's survival rate. Earn the rank of Fleet Admiral — or just have one more match. Your fleet awaits, Commander. The Republic is counting on you.
