Mortal Kombat X is a fighting game in which two players fight against each other using a variety of attacks, special moves, and gruesome Fatalities. The energy meter, first introduced in the previous Mortal Kombat game, allows players to perform techniques such as "X-Ray" special moves. Similarly to NetherRealm Studios' previous title, Injustice: Gods Among Us, fighters are able to interact with the environment, bouncing off areas to reposition themselves or using parts of the environment as weapons. In addition, each fighter has three different variations, each featuring a different set of moves they can use during the fight: for example, the character Scorpion features a Ninjutsu variation in which he wields dual swords, a Hellfire variation which relies more on fiery special moves, and an Inferno variation which allows him to summon hellspawn minions to aid him in the fight.
