In Gameradar's review of MKD, they mention a fatality. Here is the exact quote.
"Watching your character tear a couple of ribs out of his opponent's chest, then stab him in the eyes with the pointy ends, is one of the game's main attractions."
Now this could possibly mean that there will be a fatality like the one described, or they just came up with an idea of what a cool fatality might be like, just to put in their review.
If it is true and that is a fatality, it sounds pretty cool. What does everyone else think?
