Deep Sea Fishing Battle

Deep Sea Fishing Battle turns arcade fishing into a deep-sea observation mission. From the top rail of a submarine window, drag your cannon into position, aim downward, and launch visible capture projectiles into a dark ocean filled with moving fish, glowing creatures, and shifting currents.

Use sonar to reveal hidden paths, choose the right research device for each species, and build your Species Archive with every successful capture. The Device Lab explains each tool's cost, cooldown, projectile effect, and best use, while the Briefing Deck teaches rail aiming, current timing, sonar marks, and score strategy.

Designed for short offline sessions, Deep Sea Fishing Battle includes local progress, settings, fish introductions, tool introductions, game instructions, and a complete arcade loop without accounts or server dependency.
