The achievements for the highly anticipated Mortal Kombat X have been posted on XboxAchievements.com. Achievements are always a good way to get some teasers on what to expect from the game, as usually there are achievements for completing modes or doing certain specific actions that the game wants you to do, which in this case, seems to be beating the hell out of people a lot.
The most notable thing about this is found in the art for the achievements. Apparently, the character Erron Black will be in the game, judging by his appearance in the art for the Can't Stop This and Brutal End achievements. I'd say that's a safe bet.
Aside from that, there is nothing particularly revealing, but a few of them raise some questions. One that caught my eye in particular is Blanche Advantage [25g] for hitting someone with the old lady level interaction. No idea what that means, but I look forward to finding out.
Also a funny achievement for veterans is Trolling  for ducking 30 times during a fatality sequence. If you play like me, you should get that in the first one or two fatalities.
