William Neal Hallford (born October 17, 1966) is an American game designer, book author, screenwriter, and independent film director. He is best known for his work on the fantasy role-playing games Betrayal at Krondor, Dungeon Siege, and Champions of Norrath.
On October 9, 1995, Hallford was in a train wreck aboard Amtrak's Sunset Limited, westbound from Miami to Los Angeles. Unknown perpetrator or perpetrators signing themselves the "Sons of the Gestapo" left four notes on the site claiming responsibility, two of which were found by Hallford. Since that time, Hallford has appeared in two television specials about the event, When Trains Crash: Blood on the Tracks and Derail: America's Worst Train Wrecks, which were broadcast in the US, UK and Canada.
