In just a few short days Mortal Kombat will celebrate its 25th anniversary, but Mortal Kombat fans can celebrate a bit early. Warner Bros. Interactive Entertainment and DC Entertainment have recently added Raiden to the Injustice 2 roster. Players who purchased the Injustice 2 Ultimate Edition, Injustice 2 Digital Deluxe Edition, Injustice 2 Ultimate Pack, or Fighter Pack #2 can now play as either Raiden or as Black Lightning, a brand new Premiere Skin that will accompany the Raiden DLC. If you don't have the above editions or packs for Injustice 2, the Raiden DLC will be available for all players to purchase separately starting tomorrow October 6th.
