User blog comment:Jared Grace/I have found the cheats to unlock the characters in Ultraman Fighting Evolution 3/@comment-120.168.0.70-20150213225319/@comment-26939588-20160420155548

This is hard to do:
 * 1) Complete Battle Mode with EVERY Ultra in the game (even the unlockable ones)
 * 2) Complete the 10 Cities stage as EVERY Ultra in the game (again, including the unlockable ones)
 * 3) Get an A or S rank on EVERY stage in the game.

A lot to do just for one character.
