Over the weekend the official Injustice Youtube channel updated with a new trailer for Injustice 2.  The latest trailer reveals the gameplay for Raiden who will be the next DLC character that will be added to the game.  The trailer also reveals that Raiden will featuring a character skin in the form of Black Lightning.  Since both characters have similar powers it makes sense that Netherrealm Studios went with that direction. Raiden will be available for purchase in October and will be available for Ultimate Edition and Fighter Pack 2 owners a week prior to the individual release. The Black Lightning Premier Skin will be free for Ultimate Edition owners and is speculated to be available for 6,000 source crystals in Raiden’s customization menu once released.
