Submarine Rampage: Deep Sea

Your submarine is trapped in a forsaken deep-sea research station, and freedom lies in the jaws of legend. The exit key has been swallowed by the colossal Megalodon, lurking in the abyssal trench below. To escape, you must earn enough coins to transform your fragile vessel into a war machine capable of facing the beast. Hunt schools of fish and savage predators, haul their remains back to port, and trade them for precious upgrades. Reinforce your hull, load faster torpedoes, expand your ammo reserves, and prepare for the descent. Each dive takes you deeper into hostile waters where danger multiplies and survival demands sharper instincts. Only the strongest sub will endure the crushing depths long enough to challenge the Megalodon and reclaim the key to freedom.

Players control a submarine in a deep-sea environment, using torpedoes to attack fish and enemies. Earn coins by hunting, then upgrade the submarine's hull, torpedo speed, and ammo capacity at the port. The game features side-scrolling perspective, with increasing difficulty and rewards as you dive deeper. The ultimate goal is to defeat the Megalodon boss and obtain the escape key.
