LOS ANGELES – A new video game to be released today allows players to simulate the assassination of President John Kennedy.

The release of “JFK Reloaded” is timed to coincide with today’s 41st anniversary of Kennedy’s murder in Dallas, and was designed to demonstrate that a lone gunman was able to kill the president.

“It is despicable,” said David Smith, a spokesman for Massachusetts Sen. Edward Kennedy, the late president’s brother. He was informed of the game on Friday, but declined further comment.

Kirk Ewing, managing director of the Scottish firm Traffic Games, which developed the game, said he understood some people would be horrified at the concept.

“We believe that the only thing we’re exploiting is new technology,” said Ewing, a former documentary filmmaker and senior executive with Scottish developer VIS, responsible for games like “State of Emergency.”

Traffic Games said the objective was for a player to fire three shots at Kennedy’s motorcade from assassin Lee Harvey Oswald’s sixth-floor perch in the Texas School Book Depository.

Points are awarded or subtracted based on how accurately the shots match the official version of events as documented in by the Warren Commission, which investigated Kennedy’s assassination. Shooting the image of Kennedy in the right spots in the right sequence adds to the score, while “errors” like shooting first lady Jacqueline Kennedy lead to deductions.

Each shot can be replayed in slow motion, and the bullets can be tracked as they travel and pass through Kennedy’s digitally recreated body. Players can choose to see blood by pressing a “blood effects” option.
