The Defenders (Illustrated and Unabridged)

Eight years ago a nuclear war began between the United States and the Soviet Union. Within months all American survivors evacuated to gigantic bunkers miles under ground. Sophisticated, radioactivity-immune robots called "leadys" continue fighting the war on the devastated surface that is far too dangerous for humans. The Soviets have similarly evacuated underground, and each side builds powerful weapons and vehicles for the remote-controlled war they only see from film that the robots deliver.
