The game was first announced last April and was shown off with the player character running around with an A.I. companion. Given the clear Dark Souls influence, which was also stated in the title's marketing materials, it seemed likely that co-op would be coming at some point, but there have been other Dark Souls-type games without any form of co-op, so it was anybody's guess. Based on what's been said thus far, it appears co-op will be limited to just one other person that you'll be able to team up with, and it's not entirely clear how you do that. The announcement stated that the game will "gives players the chance to answer requests for help from other[s]" in order to clear out difficult areas/bosses, and that the A.I. companion would remain with you. We'll likely learn more over the next several months leading up to the game's release.
