IF anyone wanted other ways of beating Shang Tsung, Kintaro and Shao Kahn, try this way with Liu Kang. First off, with Tsung, in his Sub-Zero form, keep your distance and use your fire balls. When he morphs back into his regular form, get close and unleash combos but if you hit him one too many times, he'll throw a combo breaker. No big deal, really. In his Cage and Reptile forms, he's a bitch and just use combos.
Kintaro was easy. Stay completely away from him and when he spits a fireball, move to one side and throw three at him. When he goes into his super high jump and stomp, move to the EXACT spot he jumps from each time and use the long jump. He'll never hit you. Just keep doing the move and shot method. It'll take some time, but each time I do it, I never get hit.
Shao Kahn is the same, but you have to watch out for his shoulder charge, as it closes distance quickly and it does alot of damage. When he goes into his hammer usage mode, again utilize the move but keep the usage of fireballs down, as you are going to need to use the long jump when he starts to spin. Running away WILL NOT cut it and you'll get pounded on. He'll drop to one knee after spinning. This is where you attack. DO NOT APPROACH HIM. Use Kintaro's head and throw it at Shao Kahn's back. It hurts him pretty good. I was able to beat him on my third try with this method and was not hit once.
