But it's not abandoned. As UTC forces and rebel operatives race to seize the ship and uncover its secrets, they stumble into a terrifying revelation: the derelict is a battleground, the fallout of a long-running shadow war between ancient alien species, each more ruthless than anything humanity has ever faced.
