Trivia

 * The title of this mission, "Let the dead bury their dead" is a quote from Jesus in the book of Matthew (8:22) when talking with an unnamed disciple about following Him.
 * People at camp sites occasionally talk about a family that was eaten by a ghost in Tumbleweed and that all that was left was a glass eye. The eye Seth found may be related to the camp fire story.
 * Ironically, in the basement, Seth walks past the real treasure for Treasure Hunter Rank 4.
 * It is suggested by some (based on the comparrison between Tumbleweed in Red Dead Redemption and Widow's Patch in Red Dead Revolver) that the glass-eye found in the chest belonged to Ugly Chris; ruthless leader of the ugly gang. Chris lost his right eye from unkown causes, and now sports a red tinted eyepatch.
 * It is implied in the Undead Nightmare Gamestop preview that Seth may have unintentionally began the Zombie Plague by stealing the Glass Eye in this mission.
 * In Undead Nightmare, after John clears out the graveyards, and returns to Seth, Seth eats the glass eye.
