Operation Octo (TENOKE) Build 19952359

About The Game

Operation Octo is a tower defense action game where you play as Dr. Odin, an octopus scientist working with his dolphin colleague to destroy the skeletal invaders terrorizing the underwater ecosystems. The core gameplay involves strategically placing mechanized sea creature turrets like the Pistol Shrimp, Navy Seal, and Death Ray to fend off waves of skeletal enemies, but when defenses fail, the game turns into a frantic survival game that requires quick evasion skills.

Defeated skeletons drop various elixirs that can transform your turrets into specialized variants like ice machines, powerful mutants, or stealth weapons, adding strategic depth to your defense planning. Boss battles against massive enemies are intense challenges that will test your mastery of the game's mechanics.

Developed primarily by one person while in college, this indie game offers 7-9 hours of content with additional biomes planned as free updates. The game combines action, adventure, strategy, and casual elements with a rousing soundtrack that complements the bizarre underwater setting where mechanized sea creatures battle undead pirates in a fight to reclaim the ocean.
