- In the Golden Ending of the 1, Rogan's fiance, Sophie, survives the attack by The Chariot. And if the existence of Lisa in the third game is any indication, her survival is canon.

- In the special G ending of 4, G is shown at the site where James sacrificed himself to destroy The World. G declares that he's going to "take this fight back to the source", before telling the deceased agent that it's time for him to rest.
