One major change is the Blood Arts system, which upgrades special attacks as you continue to use them. There are over 100 Blood Arts in God Eater 2 and certain rare Blood Arts can only be unlocked under special conditions.
The attacks and Blood Arts you can use depend on what weapon you choose. Will you pick the Boost Hammer, Charge Spear or Long Sword?
God Eater 2 has new NPCs like Julius who is head of the Blood division. Alisa and Kota from Fenrir Far East Branch (and the first God Eater) return for the sequel.
