The ESRB has now rated Mortal Kombat XL on its official website. Most of the content is the same, although some new stuff have been added thanks to the addition of a new character.
The main thing that has been changed the content in Mortal Kombat XL is the addition of Bo’ Rai Cho. This character drinks alcohol and is a drunken master.
The usual content has been detailed. The game has been rated “M” with the content descriptors as: “Blood and Gore, Intense Violence, Strong Language, Use of Alcohol”
The rating summary says: This is a fighting game in which players engage in one-on-one battles against characters from the Mortal Kombat universe. Players punch, kick, and use special attacks (e.g., guns, fireballs, ice blasts, lightning strikes) to drain opponents’ life meters. Battles are accompanied by screams of pain, realistic gunfire, and exaggerated impact sounds. Large blood-splatter effects occur during fights, staining characters’ bodies as well as the ground. Additional attacks include x-ray views of opponents’ bones, ligaments, and organs shattering/bursting apart.
After an opponent is defeated at the end of a match, players can perform finishing moves called “Fatalities” that can result in impalements, dismemberment, or decapitation. Many finishing moves depict over-the-top instances of violence and gore: a character ripped in half; a character’s face sliced off with a sword; a character mauling an opponent’s torso, leaving entrails exposed. One character uses “drunken master”-style fighting, swigging repeatedly from a flask to reach higher levels of drunkenness and unlock specific moves/combos; the character’s fatality move also involves use of alcohol. The words “f**k,” “sh*t,” and “a*shole” can be heard in the dialogue.
