Octopus Invasion Demo

Get a sneak peek into the deep with the Octopus Invasion Demo — a bite-sized introduction to the full underwater adventure.

In this demo, you'll:

• Complete the Tutorial level, learning how to swim, hunt, and evolve your octopus.

• Play through Level 1, where you’ll start devouring smaller fish, unlock your first upgrades, and experience the early game ecosystem.

The demo is designed to give players a feel for the core mechanics: feeding, evolving, and exploring the ocean. It does not include later biomes, advanced upgrades, quests, or boss encounters — those are available in the full game.

Key Features in the Demo:

• 🌊 Tutorial + Level 1 gameplay

• 🐠 Hunt and eat small sea creatures

• 🧬 Unlock early-stage mutations

• 🕹️ Try both controller and keyboard/mouse support

• 🎮 Steam Deck optimized

This demo offers just a taste of what's to come — in the full game, you’ll explore six biomes, evolve along different paths, complete quests, and dominate the ocean as an apex predator.
