About This Game

Cthulhu has risen, and Chicago just became ground zero. It happens at night, the way these things always seem to. The ancient horror tears into the city, and there's nothing that can touch it. As humanity's last line of defense, you take command of a heavily armed battleship equipped with experimental weapons powerful enough to challenge the Great Old One. Fight back against the unstoppable monster, earn resources, upgrade your weapons, and grow stronger. 

How fast can you defeat Cthulhu or will he end mankind?
