Our take on Operation Octo
The page emphasizes a seven-seas adventure and future biome additions, but the current scope is 3 biomes and 7-9 hours of playtime. That gives the pitch a broader feel than the stated amount of content.
What is Operation Octo?
Operation Octo is an action tower defense game starring Dr.
Odin, an octopus scientist, and his dolphin colleague. Place sea-creature turrets to hold back skeleton enemies, including pirates, chemists, and dragons. When defenses break, gameplay shifts toward dodging attacks and surviving. The game spans 3 biomes and has 7-9 hours of playtime. New turret types become available as play progresses, and skeletons can drop Elixirs that change turrets into forms such as ice machines, mutants, or stealth weapons. Biomes introduce different hazards, including toxic pools and dark underwater areas. Special levels feature boss enemies. The vendor says additional biomes are planned for free updates.
