For some reason i am unable to unlock the following people Dairou, Hotaru, Raiden, and the "MYSTERY" person who i assume is Lui Kang-I have everything else unlocked Thank-you for your help! *and my personal secret for beating the cpu in fights-UTILIZE THE D-PAD! THE GAME IS IN 3-D for a reason, if you go in a circle just outside of sweep range you can "avoid" an attack, then quickly counter w/a combo, or a throw (depending on what kind of a fight you need it for-and it works with all matches EXCEPT FOR ONES WHEN YOUR BLEEDING AS THAT WASTES TIME) THAT TECHNIQUE HAS NOT FAILED ME YET :D HAVE FUN! FINISH HIM!
