The Nexus Arena is composed of 32 Ravens and increases and decreases based on the players action in the story.
The arena is tied into the story and each arena match helps progress the story. The ranking system in the arena mode changed from Raven Rank to a Points system which also tied into completing missions from which you get points, also with successful Arena victories. Every time a Raven is killed in the story, he or she is removed from the rankings and is sometimes replaced by a new Raven who start at the bottom.
