During the co-op game for one to four players, the group can experience a narrative-driven campaign that will enable players to explore different storylines and outcomes depending on their choices. As their chosen characters, players can upgrade their unique abilities by spending the experience points they gain, as well as unlock new powers through optional loyalty missions.
