Ascension appears in Black Ops. When Mason gets the codes in the penultimate level, the first is ascension. His last words refer to Ascension and the measures of the bullet used to kill JFK, which may be conspirators (see the laptop of someone threatening JFK). Does that refer to people that have been playing around the storyline? I'd really hate it if it was just Miller day dreaming as he gets shipped home.
P.S. The Ascension group of scientiests seen in Executive Order.
