If you haven't already, be sure to update your Soul Sacrifice game from the live area. The new version 1.30 is completely free as usual and adds 16 new quests to play. There are no new monsters or spells this time around, but the new missions will certainly be a new challenge. Once you've updated you can find the new quests in the Forgotten Pacts sections.
Its sad to see the support for Soul Sacrifice finally ending, but it was good getting all free content we did. This should pave the way for Soul Sacrifice: Delta which will have plenty of new content for us once it comes out. For now, keep playing Soul Sacrifice and enjoy it.
