Mortal Kombat X's gory fatalities are a gruesome sight, but have you ever thought about the work that goes into creating the sound effects for them? Turns out, that process is almost as gross as the fatalities themselves.

Yesterday, Mortal Kombat X developer NetherRealm held a live broadcast, "Kombatcast," where it offered some new information about the fighting game as well as a look behind the scene.

During the broadcast, NetherRealm showed some of the foley work (the process of recording sound effects) that went into the game. In the video, which you can see above, NetherRealm developers use green goo, a plunger, and some other tools to create the gross, goopy sounds you'll hear during Fatalities. NetherRealm added that it destroys a lot of vegetables, fruits, and nuts with hammers to create other sound effects.

NetherRealm also discusses how it created the game's music and other improvements it's introducing to Mortal Kombat X, so the video is definitely worth watching if you're a fan of the series.

The Mortal Kombat X release date is April 14 for Xbox One, PlayStation 4, and PC. The Xbox 360 and PlayStation 3 editions, however, have been delayed.
