The title originated in arcades, then was ported to the Sega Dreamcast, Sony's PlayStation 2, and the original Xbox through 2002 before coming to the PlayStation 3 and Xbox 360 in 2009 as a digital-only title.
Originally released in 2000, MvC2 has only seen a handful of releases through its history.
Capcom 2's lack of availability over the last eight years has eventually led to a Twitter campaign to bring back the legendary fighting game.
