GamesRadar writes: "We were able to choose from three different arenas: two from the Acolyte difficulty and one from Warrior difficulty. The two Acolyte arenas were just a mess of enemies that needed killing, with points awarded for combo chains, finishers, and insta-kills. Ninpo, the strong magic attacks from single player, are also included in co-op. Here, they can be combined, engaging both players in an even stronger attack. Meanwhile, the Warrior arena was pretty much the same as the Acolyte ones, except there was a boss fight to add to the challenge. We're hoping the rest of the Warrior arenas will also feature unique boss fights".
