• 2.1 'Outsiders'. Earth has fallen to the Cybermen, but the war has only just begun.... Across the planet the silver legions stand impassive in every city; mankind has sacrificed its freedoms for the sake of a distant conflict against its android creations, and now the price must be paid. On the streets and in the depths of space, a web of lies and deceit draws ever tighter, and the lines between human and android, between enemy and ally, are blurred. One choice remains - resist or surrender....
• 2.2 'Terror'. A secret war is raging - a war with no soldiers, only casualties.... Two species - one organic, one synthetic - face the greatest challenge to their existence: the cold logic and ancient power of the Cybermen. Earth lies trapped between oppression and destruction, and the future is shrouded in darkness. Plans are drawn, and choices are made; but the hidden truth that lurks in the shadows may be more terrible than anyone could imagine....
• 2.3 'Machines'. All war is deception. As the conspiracy of hate and distrust brings death in its wake, the sinister plans of the Cybermen are revealed, and events move on a collision course as the invaders prepare for the final phase of their rebirth. Only a handful of rebels, human and android, stand ready to confront their common enemy; but if they cannot trust themselves, then the battle is already lost....
• 2.4 'Extinction'. In the war for the future, fear is the only weapon. The Cybermen are triumphant; nothing can stand in their way. First they will absorb mankind and obliterate their android spawn; then they will stride the stars once more, to transform the galaxy into an empire of icy, flawless logic. The battle must end; only one race will emerge victorious.
