One of the trends of the last year was a shift away from including solo campaigns in multiplayer-focused games. Ubisoft's Rainbow Six Siege suffered from its absence after a history of enjoyable single-player experiences.
For Honor, Ubisoft Montreal's four-versus-four multiplayer game won't be repeating that mistake. In an update last week, producer Stephane Cardin addressed fan questions about the game.
"One of big questions we received and feedback was about the solo campaign," he says. "We said that we will have a solo campaign, and I can promise you that we will have a solo campaign. It's one of the key subjects we're working on."
