Assassin! The Game of Time Travel (1972)

Published in Conflict #3 in 1972. Assassin! is a set of rules and a "temporal trade routes" map, allowing players to use pencil and paper to track their moves and ask questions to deduce the moves of their opponents. The object is to learn an opponent's space-time travel route for three consecutive turns, and then travel to the midpoint location of that journey, and announce the time and place of your opponent's death. Published on one sheet of 8 1/2 x 11 blue paper, folded to make four pages, and stapled into the Conflict #3 magazine.
