This marks the first time the game will be available for download since December 2013, when the game was removed from PlayStation Network and Xbox Live due to the expiration of the Marvel license. Ultimate Marvel vs. Capcom 3 will also be re-released on Xbox One and PC in March 2017.
Ultimate Marvel vs. Capcom 3 was the last entry in the series to include non-MCU characters such as Wolverine and Magneto. Once Marvel vs. Capcom: Infinite is released next year, the series will shift towards more Cinematic Universe-centric characters.
