In the beginning, there is a Theatre option at the bottom (where it says Solo, Campaign, etc..)..at least I think it is Theatre... You click it and you can view just about every game you have played (not sure how many games it will save or allow you to view but so far for me, I can see every game either in Coop or Multiplayer that I have played).
When you are viewing a game you have played, you can view as any player (friend or foe) and see their moves and what happens to them .. or you can view "outside a body" (as if you are a floating camera) and move throughout the game as it is playing it out.
When you pause the action, there is an option for "snapshot".
I am still playing with it but I am impressed.
Hope this makes sense.
