Like other games under the Megaten umbrella Devil Survivor has a demon fusion system. New for Megami Ibunroku: Devil Survivor are Devil Auctions. In these events players are put in a bidding war with three computer controlled bidders. The highest price wins and in this clip the hero walks away with a Basilisk.
Here’s a look at the demon fusion system which Megaten fans should be familiar with.
