Dear Hicks,
During your playthrough of Predator campaign (with RidgeTop) you mentioned that term ''Praetorian'' came from AvP games. That made me go back and check out comic Aliens: Rogue. And in it I found ''mad scientist'' of the story, Kleist, calling bigger Aliens ''praetorian guard of the queen'' right before he enters Queen chamber to watch ''King'' fight her. Maybe, that was added in later re-releases ?
Best wishes
