Spy vs. Spy is a video game written by Michael Riedel for the Commodore 64 and published by First Star Software in 1984. A port for the Atari 8-bit family was released simultaneously. It is a two-player, split-screen game, based on Mad magazine's long-running cartoon strip Spy vs. Spy, about the slapstick antics of two spies trying to kill each other with improbably elaborate traps and weapons.
