SteamAbout Octodefense
OctoDefense is an intense sci-fi tower defense strategy game where humanity faces extinction against a colossal entity from beyond the stars. Take command of Earth's defense forces, anchor advanced tactical turrets along the invader's own descending appendages, and repel hordes of cosmic abominations before civilization collapses.
The Threat: The Day the Sky Tore Open
It was an ordinary day on Earth until a thunderous roar shook the globe and a violet rift ripped through the atmosphere. Through this dimensional breach emerged an ancient entity larger than the Moon itself, extending massive, armored tentacles down toward the surface. As governments fell into disarray and cities descended into chaos, one covert defense coalition was already prepared: the Cosmic Hostile Operations & Threat Organization.
Assuming command within C.H.O.T.O.’s fortified operations center, your directive is absolute: deploy humanity’s secret arsenal, defend critical ground points, and sever the entity’s hold on the planet.
