This game was produced for the XBOX and Playstation 2 for a VERY limited time, due to Capcom losing the Marvel license. As such, these versions of the games fetch huge prices on sites like eBay and Amazon.
Ruby Heart, Amingo and Abyss are all original characters, specifically made for this crossover.
This is the first game in the series to feature an all-new and original villain boss character that is not from any existing Marvel or Capcom universes. The other similar instance is in Marvel vs. Capcom: Infinite, with the boss character Ultron Sigma.
