Mankind's end is near. The great fortress city of Verdinani is under siege by an army of the machined dead. Metal grafted to corpses reanimating them into abominations. They ravage the lands with a raging hunger as they seek to feed their war machine. Captain Titus and three Siege Breakers are on a mission that could change man's fate. The city harbors a devastating secret, an artifact of legend capable of great power. Their mission is to recover the artifact before the dead can take the city. But time is running out and the city can only hold for so long. Bare witness to the Siege of the Undead.
