Shadow Hearts 2: Covenant Cheats

Unlock Kurando's Ultimate Weapon:
Talk to Saki at the Inugami village after the movie at the platform with Kato. Saki will give you an errand at the Dog Shrine where you will find Kurbando's Ultimate weapon.

Anastasia 's ultimate weapon:
When you have collected all 5 silver angels go to Edgar at Petrograd.

The 2nd easiest way is to either train.

the way i beat her is train,get souls, use them to get my second fire form(and other elemental forms), next i attacked the blue creature first(because i failed when i attacked the red one first),the blue one dies easier to fire crest magic,keep attacking only the blue one till it dies,next attack and kill the red one,make sure to be at full health and all,after u win you'll get fifty soul pionts.
godd luck,hope i helped.
