Spy vs Spy

Released 1984

Designed and programmed by Michael Riedel for the Commodore-64 with Atari 800 version ported by Jim Nangano. It is a two-player, split-screen game. It would be later ported to most if not all the computers and game systems extant at the time. According to Wikipedia: "The object of the game is to collect various secret items in a briefcase and exit the building through a door to the airport, either before the opposing player exits or before the timer runs out. While searching for the items, traps can be laid to take out the opponent (or the player himself, if careless). Each spy has a personal countdown timer which depletes by 30 seconds upon each death."
