You have to defeat each Character Bad Side and Relive the Good side
Errr, The way I did it was . . I went online and Got a map of it and I drew It, And Every time I did a person I would bilog them, It was Easyer But still quite Hard
If you CBA or Can't draw, I'll send you the link to the map that I copied, it gives you The paths of Which Each door goes, tell you where the Bosses and So on . .
first, check the map then u will see purple spots go to where the purple spots are. there will be a door with purple fog go in the door defeat the evil clones when ther are no madami purple spots on the map, try to find a spot where there are boss trophies keep pressing up but its gonna take some time to get in there inside is THE FINAL BOSS!
