Big question.
If NT and Capcom said time and time again that they're just working on Dante's story and Vergil will not be a playable character, who made this?
The demons sure do look different. I mean I hope they appear in DmC's main campaign, but Vergil seems to have everything Dante doesn't.
Those things being a teleport (00:47), Dopplegänger style (01:06), and a quick ground Trickster dash (00:57).
EDIT: C-U cleared that up.
Maybe NT started work on it a couple months ago, but this chapter definitely won't be out by the time the game is released.
