Mobfish Hunter is a mobile game in which the player dives into the depths of the ocean to catch unusual fish (not to be confused with a typical Fishing Mini Game, where one stays on the surface with a fishing pole). The gameplay is inspired by Radical Fishing and its sequels— first, the player dives as far as possible, dodging obstacles and fish by tilting the phone. As soon as you hit something (or reach the bottom), the diving craft turns around and heads back up— in this stage the craft is invincible, and captures any fish it can catch along the way.

The game has a variety of different levels and locations which the player can dive in, each with a different theme and different fish available.

Tropes

• Alien Sea: Some of the levels have strange colored water and unusual rock formations underwater.
• Awesome Underwater World: The ocean world is very colorful and interesting.
• Diesel Punk: The technology and setting have a 1940s/50s retro-futuristic vibe, with lots of rivets and curved steel. Everything appears to be gas or diesel powered as well.
• Eldritch Ocean Abyss: The deeper ocean creatures get very strange looking, invoking both real-life deep ocean creatures and eldritch myths.
• Endless Running Game: You dive at a steady pace dodging obstacles until you hit something.
• Freemium Timer: You can buy more power for diving, or wait for the energy meter to refill.
• Gotta Catch Them All: The goal of the game is to collect all possible fish.
• Money Grinding: The best way to get difficult deep-water fish is to do lots of shallow dives to collect gold and power-ups, then spend them all at once.
• Ocean of Adventure: Since it's a diving game about exploring the ocean, there's lot to do and fight underwater.
• Shout-Out: One of the fish is Laboon from One Piece.
• Toxic Waste Can Do Anything: The fish in Industrial Park are mutants, with many eyes or weird limbs. The hub screen shows a pipe dumping some kind of black sludge directly into the ocean right above it.
