Dreadnoughts of Caelus is a first-person 3D action flight sim. Far from Earth, a city floats in the bottomless blue-green mists of the ice giant Caelus, its inhabitants lost in dreams. A dreadnought is coming for them, an immense ship dwarfing your jet fighters. Can you stop it in time, or will you just chip off some of its resources to strengthen your defense of another city? Featuring fully destructible dreadnoughts with multiple systems to target, to weaken its defenses, slow it down, degrade its capabilities, liberate its resources, and eventually send it plunging into the depths of Caelus.
