ExZeus is a heavy action 3d shooter in the style of the classic hit "Space Harrier" from Sega. The Player has a choice of playing three different robots, "Sofia" a male robot with average speed and shield protection, "Calista" a female robot with a high speed but a low shield protection, and "Dynamis" a heavy "male" robot with low speed but high shield protection. Those three robots are leaders of a Special Squadron team having been called into an "invaders alien" destruction scene.

The Player pursues the traditional goals of defeating enemy ships and saving the world. During the course of the action there will be many explosions, lasers, mega-bomb and special effects.
