Mortal Kombat II's hidden beauty Jade was confirmed by Game Informer back in early January [full story] and the existence of a classic themed alternate was confirmed as a bonus for purchasing the re-release of the first two Mortal Kombat movies on Blu-ray [full story].
NetherRealm Studios have provided a a high quality glimpse of the retro Jade design:
The attire pays homage to Jade's first playable appearance in Ultimate Mortal Kombat 3, rather than her first appearance as a hidden fighter in MK2. This is in contrast to Ermac, who uses the MK1 model for his classic costume [full story] which raises the question whether or not fellow femme fatales Kitana and Mileena will employ a recoloring of this model rather than their MK2 models if they are also given retro DLC costumes.
Mortal Kombat and Mortal Kombat: Annihilation are officially released on Blu-Ray the same day as the new game, April 19. The Blu-Ray Jade "classic" DLC bonus is available exclusively for the PlayStation 3 version of the game. The costume is expected to be made available to all owners of the game, at a later date.
