This is according to a tweet by NetherRealm’s Ed Boon in which he confirmed that the Tanya DLC is on its way and it should be released in early June. No specific dates were mentioned by Boon seemed to be pretty confident about its release, so we guess in the meantime we will just need to keep an eye out for it.
That being said, fans of the Mortal Kombat X franchise should be familiar with Tanya. The character has made appearances in various Mortal Kombat titles, with the most recent one being Mortal Kombat 4. Tanya was confirmed for Mortal Kombat X when her finishing moves were spotted in the game, so it was really a question of when, not if, she would be appearing in the game.
Other confirmed characters coming in the DLCs include Predator and Tremor which will be part of the Kombat Pack. Boon had also previously teased that Rain might make an appearance, and thanks to a modder several characters such as Rain, Sindel, and Baraka were also made available.
