Operation Octo Build 19952359 (upd.12.09.2025) - TENOKE

Operation Octo is a tower defense strategy action game where you control an underwater defense against ancient forces awakened in the depths of the sea. A genius octopus has constructed an army of bioturrets to stop the invasion. It's time to command the depths. Your task is to correctly place turrets and react to enemy mutations in real time. Skeletons do not just attack, they evolve and require changes in your strategy. A mistake does not cost you resources but control over an entire biome. Unlock new types of towers, combine their effects, strengthen them with elixirs. Change configurations on the fly and do not let the enemy adapt. Plan routes, protect key points and prepare to clash with sea bosses.
