JFK Reloaded (PC Games, 2004)

Gamers play a sniper firing on the president's limo in a simulation that features physics, movements and conditions accurate to the actual shooting. The game uses the unanswered details of the event and attempts to pose the question: could Lee Harvey Oswald have murdered John F. Kennedy from the sixth floor of the Texas Schoolbook Depository? The publisher offered a $100,000 prize in an online competition for the player who most closely matched the shots taken by Lee Harvey Oswald, as concluded in the Warren Commission Report on the assassination of JFK.
