Onimusha was a very important game for Capcom during the PS2 era and it looks like they want to give it another shot on the current generation. IGN conducted an interview with Ono where he said that he feels that the time is right for them to bring it back. He does feel that they need to do something new with the francise to make the comeback worthwhile. Ono said “I think it might be time to progress beyond the standard single-player adventure. There should be ways to expand upon what we’ve done while involving the community more. Perhaps implement some sort of multiplayer into a game like that.”
I can’t imagine what kind of multiplayer they would add to Onimusha, but I am always interested to see something new and unique in the multiplayer space.
