Marvel vs. Capcom 2: New Age of Heroes (a.k.a. Marvel vs. Capcom 2 or MvC2) is the fourth and final game in the Marvel vs. Capcom series of fighting games. With the final installment of the series, Capcom simplified the engine so that it would be more accessible to casual players, in order to bring in new players. Changes were made to the air combo system and the button configuration was trimmed down to 4 main buttons and 2 assist buttons.

The game also features 3 on 3 tag, compared to the 2 on 2 tag from previous games in the series. It is the only game in the series to use the NAOMI system, which is used mostly for 3D games. It is mainly seen in this game in the backgrounds and system effects, as well as Abyss’s sphere. Marvel vs. Capcom 2 was later ported to the Dreamcast, Xbox, and PlayStation 2.
