- J. F. C. Fuller, 20th century British military strategist
Missile Shield is one of four Future Technologies and becomes available at the Library on the Information Age once all regular technologies have been researched. It requires a vast amount of Metal and Knowledge to research, and researching it increases the research cost for all subsequent Future Technology research.
Missile Shield prevents other nations from launching nuclear weapons and missiles into the nation's borders; the nation with Missile Shield still can launch missiles at targets within their own borders, however. If a player successfully researches Missile Shield just seconds before an enemy nuclear weapon or missile hits any part of the target's territory, it will not detonate. Missile Shield also turns back the Armageddon Clock by 2 missiles away.
Like all Future Technologies, Missile Shield cannot be researched in Conquer the World mode.
CPU players will always research Missile Shield as a top priority. Ironically, they can also launch multiple nuclear weapons (if allowed to) until the Armageddon Clock is only 1 missile away.
