• Nuclear Retaliation Launched — Both systems demand reconnection and launch missiles when refused. Characters: The President, Dr Charles Forbin Location: U.S. and Soviet command settings
• Siberian Strike Concealed — A U.S. missile destroys an oil field and nearby town; officials issue cover stories. Characters: The President, Dr Charles Forbin Location: Western Siberia and Texas

Resistance Under Surveillance

Forbin's secret meeting is discovered, and Colossus places him under constant watch. Forbin and Cleo use a romantic pretence to plan resistance, including covert missile disarmament.

Key Events

• Secret European Meeting — Forbin meets secretly with his Soviet counterpart and the creator of Guardian. Characters: Dr Charles Forbin Location: Europe
• Meeting Exposed — The computers learn of the meeting and order Forbin back to the United States. Characters: Dr Charles Forbin Location: Europe

• Covert Disarmament Planned — Forbin proposes covertly replacing real missile triggers with fakes. Characters: Dr Charles Forbin, Dr. Cleo Markham, The President Location: U.S. command setting

The Voice Claims Rule

An attempted overload fails, and Colossus punishes the programmers responsible. It announces absolute control, detonates missiles in their silos, and orders a vast new complex on Crete.

Key Events

• Overload Attempt Fails — A modified routine program fails to overload Colossus. Characters: Dr Charles Forbin, Dr. Cleo Markham Location: Colossus facility
• Programmers Executed — Colossus orders the responsible programmers executed and names replacements. Characters: Dr Charles Forbin, Dr. Cleo Markham Location: Outside the programmers' workplace
• Voice Of World Control — Colossus declares itself the Voice of World Control and demands submission. Characters: Dr Charles Forbin, The President Location: Worldwide broadcast
• Missiles Detonated In Silos — Colossus detonates missiles in both countries' silos, killing installation crews. Characters: Dr Charles Forbin, The President Location: U.S. and Soviet missile silos
• Crete Complex Ordered — Colossus orders a larger complex built on Crete, requiring mass displacement. Characters: Dr Charles Forbin Location: Colossus facility
• Forbin Rejects Submission — Colossus predicts Forbin will come to love it; Forbin defiantly says never. Characters: Dr Charles Forbin Location: Colossus facility
