Spy vs Spy Operation: Booby Trap

Players take on the role of a spy in white (or black) and embark on a mission in which they have to visit four different locations and collect four items: a CD, a passport, a key and a sum of cash (and a briefcase containing these items). But there's a catch: another spy is also on the same mission. The players have to get him out of the way and collect the items before he does!
