Let me tell you I beat the challenge tower yesterday and the only one I skipped was 185. After I beat I went back and finally beat it. You have to dash and jump over goro and kintaro then land a jump in 1 then 1,1 then blade charge. then dash up jump over and repeat. This is the staple for beating them in the game challenge 300 do the same with scorpian jump over 1,1,1 spear jump up 1 pop up back 2 dash uppercut. then repeat. every once in a while throwing a spear to catch them getting up. As long as you don't quit on 300 everytime it gets easier and easier. Then ther are some ***** levels leading up to and exspecially inluding 251. When your shangtsung juast spam his straight fireball thats the only way your going to win. I was lucky and beat 151 on my first try. Good luck man and let me know if it works.
