Mortal Kombat X has had a truckload of DLC added to the game since its launch. The good news is that you can pick and choose what you want as it's rolled out while the volume also makes the value of the Season Pass rise a whole lot. Having said that though, it means after buying the game, you are already missing out on a fair bit of content of you don't want to pay more.
But here is something you won't have to buy. NetherRealms are adding extra content in the game today for all players. The Klassic Fatality Pack 1 is being rolled out meaning that everyone will get access to four new fatalities from the first Mortal Kombat. These are for Sub-Zero, Scorpian, Sonya and Johnny Cage. You'll get the Kold War skin for Scorpian too, again for free.
To see each of these iconic Fatalities performed for you pleasure, take a look at the video below. These certainly bring me back.
