Nephilim, SoS, DmD, and Heaven or Hell all cleared.
Heaven or Hell mode has all missions SSS rank.
All upgrades unlocked.
All secret missions completed.
All Lost Souls found.
Save slightly modded to have max items (10 of each Star & 3 Gold Orbs)
Having Super Dante makes getting SSS easier on the other difficulties, I'm working on an all mission SSS save.
