Storyline
Instead of possessing a single overarching story, Nocturne's gameplay is broken up into four independent Acts. Each Act is a self-contained campaign that can be selected as soon as the game begins. Although the four Acts can be played in any order, they progress in chronological order from first to fourth, so some minor details, such as which agents join or leave the Spookhouse organization as time passes, are easiest to see when the Acts are played in order.
