As reported by VideoGameWriters, Capcom has revealed in an interview with Famitsu that DLC will be arriving for Ultimate Marvel vs. Capcom 3.
Capcom revealed that the DLC would include new costumes, a new single player mode and other things. It’s surprising to note a new single player mode is to be included as DLC and not in the game itself. Nevertheless, the option for more costumes should be good as a lot of alternate costumes were released for both Street Fighter IV and Super Street Fighter IV.
Capcom stated the reason it was not released as DLC was because of the Japan Earthquake that affected some of its staff members. Still, I would have liked some new characters for the game other than the 12 new ones that were included with Ultimate Marvel vs. Capcom 3.
