Gun Metal is a 3D shooting video game for the Xbox and Microsoft Windows where you take control of the fully transformable prototype combat vehicle.

The game is based around a war (sometime in the future) on a planet called Helios, where humans have settled.

Project Gunmetal is a massive operation which oversaw the creation of a supremely powerful war machine.

In its primary form, a walking "humanoid" mech many dozens of feet high, it possesses a range of 24 weapons and an electronic shield.

As you progressing through the game, additional weapons are unlocked allowing the player with multiple loadout options, providing more replayability and alternative combat engagement.
