Just started out on Dante’s Inferno? Need some souls before descending down to Hell?
Go no further than Xbox LIVE Marketplace where you can download Soul Packs of various quantities. As an incentive, there is a pack of 500 souls that is downloadable for free.
In my opinion, these downloadable soul packs are not necessary in the beginning. Within 10 minutes of enemy encounter on each stage, it’s easy to accumulate more than 1,000 souls.
Perhaps they become handy whether you are starved for additional souls just before a boss battle, and you need some souls in order to be able to purchase a desired upgrade.
