Nuclear War is a single player turn-based strategy game developed by New World Computing and released for the Amiga in 1989. It presents a satirical, cartoonish nuclear battle between five world powers, in which the winner is whoever retains some population when everyone else on earth is dead.
The introduction includes a homage to Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb
Each player - one human, four computer-controlled - is represented by a caricature of a national leader. If there is a computer-controlled winner at the end of the game, that leader is depicted jumping for joy in the middle of a blasted wasteland, crowing "I won! I won!". If the player wins only the high score board is shown. Once a player (computer or human) loses, all of their stockpiled weapons are automatically launched. It's possible for a game to have no winner because of this. If this happens, a cut scene of the earth shattering and exploding is shown, and the high score table appears (though without any new entries.)
