A masked psychopath named Kabal uses twin sickles to disembowel his opponent while he rips their skull in two. D’vorah, a bipedal insectoid, uses her acid breath to impregnate the enemy with a spider, who’s legs and head rip out from their dismembered body. A green ninja named Jade uses her staff to dislocate both of the enemy’s arms, ripping their head from it’s spine and showing off the oozing face to the camera.

These aren’t scenes from a snuff film, they are just a sampling of the Fatalities (end of match finishing moves) available to players in Mortal Kombat 11. Releasing on April 23, developer NetherRealm Studios takes the franchise’s infamous gore and violence and turns it all the way up. With the most polished, detailed models of blood, bones and visceral guts, MK 11 is so realistic it’s delighting fans and, unfortunately, fooling algorithms. It seems YouTube’s algorithm can’t tell the difference between MK and real life gore, to the detriment of the creators who need their content to find viewers.
