Do you all know really wat ur talking about?...the person with the arm, is Nero, not Dante, or Vergil...and, Dante and Nero are agaist eachother, well, its more like Nero not liking Dante. But ya, Nero's arm is posesed by an evil foce, and he dosent know wat kind of powers it contains. during the game he wears his arm in a sling to keep it away from site. But of corse it wont be posible to hide it any longer,and thats wer he discorvers his powers with it. The arm's powers will be used use ALOT in the game,the things u can do with it are like: regardless of enimies air born or on the ground, u can grab enemies from a distance and pull then towrd u, or push them away into other foes, and even slam them into the ground...u can also combine other moves with this, for example, one move involves a classic DMC move, "the stinger"(lunging the sword at a foe),,,well, in short this means that the arm brings them to u, u do the move,and then the arm again bringing them tword u again,together one after another, wich should be enough to get any fan salivating...!...........!......-_-...
