Description

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.

Installation Guide

Step-by-step setup process for TENOKE

Mount the .iso image — Windows 10/11 mounts it from the right-click menu, otherwise use Daemon Tools or a similar tool.
Run setup.exe from the disc and install the game — Tenoke builds are already cracked, installation is all it takes.
If the disc contains a Tenoke folder, copy its contents into the installed game directory.
Launch the game from the desktop shortcut (as administrator).

Having trouble launching the game?

Check these common causes before troubleshooting further.

Add the game folder to antivirus exclusions before installing — the Steam emulator files inside are frequent false-positive targets.
Block the game .exe in Windows Firewall and do not sign into Steam with the cracked build.
Install the runtimes from the disc's Redist folder if the game reports missing DLLs on first start.
