Intended as an expansion set for Nuclear War, this game can be played separately or shuffled in with Nuclear War to make a bigger game. It brings the devastation up to date with cruise missiles, MX missiles, new Special cards, sneaky Spies, and Space Platforms. (And don't forget Skippy the feared SuperVirus). This game won the H G Wells Award for best SF Boardgame of 1983 awarded at Origins 1984 even though it is a card game!
