About This Game

How on earth did it even start? They were originally just two otters meeting by chance on the beach. One loved throwing rocks; the other loved fishing. Then a rock knocked the fish flying. An argument. A tsunami. "We're gonna be swept apart!" And so, two otters who usually wanted to punch each other on sight had no choice but to hold hand—wait, no, get tied together by seaweed—and stumble into a mysterious underwater world. Welcome to this rather reluctant otter adventure! Otter Chaos is a local/LAN co-op action-adventure game. You and a friend will respectively control two otters with completely different personalities, roles, and combat styles as you explore, fight, solve puzzles, gather resources, buy equipment, and grow stronger in the undersea world. The core of the game is two-player cooperative combat.

🦦 A Pair of Sworn Rivals

  • Local/LAN two-player co-op adventure.

  • Two players control two drastically different otters:

    • Stone Otter: Ranged, tsundere, sharp-tongued, and mischief-prone. His favorite hobby is playing with rocks—and teasing Angler Otter.

    • Angler Otter: Melee, quiet, reserved, and a hardcore angler. His ultimate wish is simply to never come back empty-handed—and to stay as far away from the guy above as possible.

  • Sounds like great teamwork... right?

  • Story: From a beach mishap to an underwater adventure, follow two rival otters as they bicker, cooperate, cause trouble, and save each other, experiencing a story about "a tiny bit of friendship."

🌿 Bound by Seaweed Fate

  • Throughout the journey, the two otters are tethered by a single piece of seaweed.

  • It is both a bond and a tool—helping you cross obstacles, or knotting you up in place if you make a wrong move.

  • Want to clear the stage smoothly? First, learn how not to drag your teammate into a ditch.

  • Seaweed Tether Mechanic: The otters remain linked throughout the game. It functions as both a bond and a utility to cross gaps, trigger mechanisms, and pull each other around.

⚔️ Fight, Level Up, and Quarrel Along the Way

  • Explore unknown regions in the mysterious underwater world and tackle bizarre enemies and stage mechanics.

  • Work together to defeat monsters, level up, collect resources, buy gear, and grow stronger.

  • Of course, the real challenge might not come from the monsters...

  • But rather from:

  • Your teammate.

  • Being the smart one alone won't get you anywhere here.

  • Underwater Level Exploration: Features multiple undersea regions and stages. Players must platform, dodge hazards, solve environmental puzzles, deal with stage mechanics, and explore uncharted areas.

  • Combat & Enemies: Face a variety of weird enemies using distinct combat styles and roles. Ranged and melee must cover each other to progress.

🦦 Game Features

  • Two-Player Co-op Adventure: Local / LAN multiplayer with two players controlling the otter duo.

  • Seaweed Tether: The two otters are tightly bound together by seaweed...

  • Rich Level Mechanics: Various weird and fun underwater mechanisms that test your chemistry.

  • Combat & Gear Progression: Explore the seabed, gather resources, purchase gear, and become stronger!

  • Cute & Chaotic Daily Life: If you end up fighting your friend, please don't leave a negative review!

The current version includes core features such as 2-player co-op, two playable otters, the seaweed tether mechanic, basic combat, level exploration, resource gathering, gear purchasing, and character progression. The game is still in active development, so bugs, balance issues, or missing content may occur. We plan to add more underwater regions, enemies, level mechanics, equipment, story content, and multiplayer optimizations in future updates. Specific update content and schedules may be adjusted based on development progress.
