It looks like new characters are joining the roster of NetherRealm Studios new "Mortal Kombat" game, "Mortal Kombat X" along with a set of the game's achievements.

According to VG24/7, a complete list of "Mortal Kombat X's" game achievements were leaked online courtesy of Xbox Achievements. What is more interesting about the leaked game achievements is that it also revealed three characters that were not announced by NetherRealms Studios.

According to Test Your Might, several screenshots that were posted in the website features Baraka, Shinnok, and Erron Black. IGN further adds that Erron Black first made his appearance in the "Mortal Kombat X" comics, while website hinted that the Tarkatan warrior seen in the screenshots could be Baraka himself although NetherRealm Studios has not yet confirmed if its him in the photo.

Finally Shinnok has made his return in the "Mortal Kombat" game. The fallen Elder God made his appearance at the end of "Mortal Kombat" reboot game in 2009, and has since re-appeared in the "Cage Family" trailer of the game.

"Mortal Kombat X" senior producer Adam Urbano told PlayStationLifeStyle.net about the possibility of having new characters in the game.

"I hope so. I think our strategy is pretty well known at this point. The production team likes to find ways to make it so they can work until the last possible second to sneak on more and more content," Urbano said. "So, at that point when we are done, we are close, about a month or so, then we start to look at all the fun stuff we couldn’t get to because we love these games and would work on the forever if we could. Well, we do, it’s just over the years."

NetherRealm Studios revealed last week the inclusion of Jason Voorhees to the game's roster as well as Warner Bros. announcement of having two more characters besides him in the"Kombat Pack" season pass, which cost around £24.99 ($36.95).

VideoGamer previously reported that the "Predator Pack" will be available in June, which features the Predator and Colonel Al Dillon.
