Even though some of the content in Mortal Kombat vs. DC Universe has been censored for American audiences (read: The Joker's fatality!), it looks like Europe will be getting a more mature version.
Hans Lo, the game's senior producer, offers the following explanation:
"That's partly true [that the fatality has been edited]... You know, for North America we have a Teen rating, and teen really means 13 and above. Thirteen is pretty young, you have to admit. For Europe we have a 15, 16+ rating - so it's a bit different."
So there you have it, America. Our teens are officially too young to watch a beloved comic book character shoot somebody in the face in a video game. You'll understand when you're older.
Or you'll just import the European version...
