A special 'Rent' version is known to exists as "X-Men - Children of the Atom [Yellow Board]
It is the first fighting game produced by Capcom using characters under license from Marvel Comics, widely praised for its faithfulness in capturing the spirit of its namesake comics, by using colorful animation and voice actors (see Staff section for more information) from the 'X-Men' animated series.
All characters are coming from Marvel comic books (except Akuma) :
Akuma ('Gouki' in Japan) - "Super Street Fighter II Turbo
" (Super Street Fighter II X - Grand Master Challenge" in Japan)
Colossus (aka Piotr Nikolaievitch Rasputin) - Giant-Size X-Men #1
Cyclops (aka Scott Summers) - X-Men #1
Juggernaut (aka Cain Marko) - X-Men #12
Iceman (aka Robert 'Bobby' Drake) - Uncanny X-Men #1
Magneto (aka Erik 'Magnus' Lehnsherr) - X-Men #1
Omega Red (aka Arkady Rossovich) - X-Men #4
Psylocke (aka Elizabeth 'Betsy' Braddock) - New Mutants Annual #2
Sentinel - Uncanny X-Men #14
Silver Samurai (aka Kenichiro Harada) - Daredevil #111
Spiral (aka Rita Ricochet) - Longshot #1
Storm (aka Ororo Munroe) - Giant Size X-Men #1
Wolverine (aka James 'Logan' Howlett) - Incredible Hulk #180
Unlike previous incarnations of X-Men video games, X-Men - Children of the Atom also allowed players to helm popular X-Men villains, such as Omega Red; the mutant hunting android Sentinel; Spiral, lackey of Mojo; and Silver Samurai. Also, because this game was released around the same time as "Super Street Fighter II Turbo
", programmers also included Akuma (see Tips And Tricks section for more information).
The game, along with SSFII Turbo, is considered as one of the first fighting games to popularize the now often-used ideas of 'Super Jumps', 'Super Combos', and 'Tech. Hit', which meant that an attempted grab or throw had been negated by the opponent. Furthermore, the game was the precursor to the Capcom 'Vs. series', with elements and characters from this game having been combined with "Street Fighter Alpha - Warriors' Dreams" to create "X-Men vs. Street Fighter".
Sony Records released a limited-edition soundtrack album (X-Men Arcade Game Track - SRCL-3120) on March 24, 1995.
