But "Conviction's" arguable shining moment happens during a collection of two-player (online or splitscreen) co-op missions that doubles as a prequel to "Conviction's" single-player story. (Quick aside: No competitive multiplayer. Sorry.) Neither player stars as Sam, but the full complement of his abilities lay at both players' disposal, and coordinating stealth attacks with a teammate opens the door to numerous strategic possibilities that aren't possible when fighting alone. Solo players can engage in most of this content by themselves if they prefer, but modes centered around cooperation - storyline portion included - are off-limits without a second player.
