In a private message on the Ubisoft Forums, community representative UbiJurassic had confirmed that For Honor requires a persistent online connection at all times, during the campaign as well. We also learned in October that the game will not have split-screen which was originally planned. So there has been a lot of changes regarding For Honor.
We can confirm that For Honor is an always online experience. Some elements of progression, which is hosted online, are shared across story and multiplayer modes. Players will need to be connected to the Internet at all times to play For Honor.
It’s a bit weird how that has changed because a few months ago Creative Director Jason VandenBerghe said this:
We built the campaign so that if you bought the game just for that, that you would be satisfied even if you never went online and played multiplayer,” he said. “It’s intended to be a full experience.”
For Honor is to release on February 14, 2017 on Xbox One, PlayStation 4, and PC.
