Go to the Krypt, hit start and go to kollection. Select character viewer, scroll down and click on Johnny Cage, Kano, Kung Lao, Liu Kang, and Sonya. Kung Laos new costume is da best.
Wait... Why does Liu Kang's "MK1" costume look more like his MK2 costume? In MK1 wasn't he just wearing plain black pants? No headband or wristbands? I'm pretty sure in MK2 he had the red headband and belt, and the wrist gear.
