Get All Eight of Your Tentacles Ready as Tower Defense Game Operation Octo Launches Next Week

Klub Kofta Studio has just announced that its tower defense game, Operation Octo, launches onto Steam on September 10th, 2025 for Windows, Mac and Linux (with full Steam Deck support). 

In the game, players join Dr. Odin, an octopus scientist on a quest to stop the evil skeleton army that threatens the marine ecosystem. The game combines bull-hell inspired mechanics with strategic turret placement as you dodge oncoming waves of enemies. 

As you progress, you’ll explore three biomes each offering unique hazards and environmental challenges designed to keep you on your toes (or your tentacles!). Upgrade your arsenal and gain allies to fight with you against the skelly threat.

Operation Octo launches on September 10th for $5.99. You can wishlist the game on Steam to stay up to date on future news and try out the demo now.
