Anyone who has played the Mortal Kombat 9 demo has probably look at the bottom left and right of the character selection screen will notice 2 DLC icons well the cat's out of the bag and now the identity of these two characters is now known:
"[The two we're adding] are Kenshi, who players will recognise from previous MK games, and more excitingly we're adding Scarlet.
"Anyone who knows the history of Mortal Kombat will tell you that back in the days of the arcade - when they did just palette swap characters to come up with multiple fighters in the game - there was a glitch in one of the old arcade machines that caused the Jade/Katana/Milena female ninja to glitch and turn red.
Another character said to be planned for the fighter is MK2 sub-boss Kintaro. Netherrealm said it'll continue to work on DLC for Mortal Kombat "as long as people are playing it".
Kenshi is one of the characters introduced in the PS2 versions of Mortal Kombat games just for clarification sakes here is him demonstrating his fatalities:
And Scarlet was believed to be a glitched character in Mortal Kombat 2, she is basically a Red Mileena / Kitana / Jade but now she is being made in to a real character and of course like every other MK character the DLC characters will have unique fighting styles, fatalities and X-Ray moves.
Mortal Kombat 9 is set to release on April 19 US and April 21 in UK no news on the DLC prices but hardcore fans will definitely grab the characters for an upper hand in online gameplay.
