Xbox360achievements.org has revealed the Achievements one can accomplish in Mortal Kombat vs. DC Universe, and as a result have also revealed as of yet unannounced characters by Midway! Achievements, as XBox 360 owners know, are a way to improve your Gamer Score on XBox Live. Games have a list of Achievements varying in difficulty and each such Achievement you complete will reward you with a set number of points. In MKvsDCU, many Achievements deal directly with mastering particular characters on the game's roster. Embedded in this list of characters, presumably a list of all the playable characters in the game, are the final four characters that had yet to be revealed. From the Mortal Kombat side of things, the nomadic Tarkatan Baraka and the emperor of Outworld himself Shao Kahn join the cast. From DC, Superman's arch nemesis Lex Luthor and cosmic force Darkseid step into the light.

Among the list of Achievements rests one that awards 100 points, tied for the largest in the game. "Special Moves Pro" Achievement states, "Do all special moves including jf’s". It is currently unknown what "jf" stands for, but it likely is not a character.

We have contacted Midway in attempt to confirm or deny this story, so any confusion may be put to rest.

EDIT: We have received official confirmation from Midway that this story is legitimate. An update will be forthcoming.
