Around 1992-93, Street Fighter II was breaking the bank in arcades with its balanced one-on-one fighting system. It wouldn't be long before there would knock-offs attempting to get a piece of those arcade profits. The most prominent of these would be a Taiwanese ROM-hack, dubbed by players today as Street Fighter II: Rainbow Edition. Rainbow Edition payed no mind to balance or even the basics rules of fighting gameplay, as players could input crazy and broken moves for each character, or even switch between characters mid-round to achieve victory at lightning speed. The ROM-Hack would gain popularity over time however because of its tendency to flip the bird at rules and standards. Pressured not to lose to such a half-assed clone, Capcom would go on to release several 'updated' versions of their game that 'coincidentally' included balanced versions of some of the actions presented in Rainbow, such as Dhalsim's teleport, Chun-Li's fireball, and especially its faster-paced combat. Despite its obviously broken aspects, the game is still well-received by players as an over-the-top lightweight bopper with none of the pressures that come from the real deal.
Fast-forward to Tokyo Game Show 2014, where Capcom announced that it will be traversing to the other end of the rainbow, as Ultra Street Fighter IV will be receiving free DLC in the form of a new mode called Omega Edition later this year. In short Omega Edition can simply be dubbed Street Fighter IV: Rainbow Edition; not built for balance at all, but for pure unorthodox fun. The mode can be played both offline and online (but in a non-ranked setting), and will incorporate crazy versions of each of the 44 characters' individual movesets. Peter "Combofiend" Rosas demonstrates just a sample of just how broken things can potentially be in the new mode in the video below.
