ok...well people say that they have glitched the game to get the SU's without unlocking them....but i dont believe it..the theory works out..just takes time i dont have......
the theory was:
to go to practice...and pic scorpion as your characer..and then the foe curser will come up on sub-zero..and u hold up and press x/a...and itl lag and take like 5-8 seconds to pic sub zero...and the koding gets messed up and ur not scorpion when u start..u get randomized..people say they have been rain, goro,,etc...but i dont believe it....so try it yourself

ok thx

rain is in the game... well not playable hes in outworld and he asks for a mission... i think 2 missions im not sure but hes not playable

Yeah youre right, he asks for a special knife
Hes also in edenia, but i forgot his quest.
