For 200 years they lay deep beneath the earth and silent on the ocean floor. Now, two opposing armies race to unearth these massive machines of war, the devastating weapons known as Decimators. As more of these vast robots are reactivated, the world moves ever closer to another all-out-war, drawing innocent victims into the deadly conflict. One such innocent is Lean, a young mechanic working on a routine excavation of a submerged Decimator. Routine that is, until an ambush by the hostile Zafrins forces Lean to pilot the armor in order to survive. The ensuing battle changes Lean\'s life irretrievably as he sets out on a risky mission to infiltrate a secret Zafrin base and eliminate their Decimators. Deep in enemy territory, the mission goes horribly wrong and Lean is hurled into a whirlwind of subterfuge, intrigue and relentless gunfire.
