Humanity has ships. You have tentacles. Rise from the deep, break the navy, and chase one more run.
You are the monster beneath the waves.
CTHULHU is a dark, hand-painted arcade game where humanity is the enemy and the ocean belongs to you. Rise from the abyss, smash ships with your tentacles, and dive before the depth charges find you. The longer you survive, the harder the world fights back - fishing boats give way to patrol boats, destroyers, submarines, minefields, and finally the entire navy.
