There are more than twenty playable characters to choose from, the majority of them edited versions of characters from classic Capcom fighting games like X-Men: Children of the Atom or X-Men vs Street fighter, although many have been created from scratch or by using partial graphics from other games. X-Men Second Coming is a 1-v-1 two-dimensional fighting game that uses the MUGEN engine to recreate spectacular combats between the most famous characters in Marvel's X-Men.
