During their pre-gamescom even today Capcom announced that Dante’s brother, Vergil will be making an appearance in DmC: Devil May Cry. He returns to recruit Dante into a group known as the Order to help him destroy a demon only interested in enslaving mankind. So yes, for the first time Dante and Vergil will be fighting alongside each other instead of against each other, which was demoed by Capcom in a trailer at the event. The two brothers also were shown arguing over the game’s female character, as well as their methods on how to complete the mission.
DmC: Devil May Cry is coming to the PS3 and Xbox 360 in January 2013.
