Arkane's Dishonored series will be going on a hiatus as dev looks to focus on multiplayer games
Arkane Studios is a development team with branches in both France and Texas, where they create popular Bethesda-published franchises such as Prey and Dishonored. Their latter series, Dishonored has seen critical acclaim in the three releases it's seen since its its inception in 2012. However, it looks like the studio wishes to move on from those games and focus on something new, according to an interview with VG247. Arkane's lead designer, Ricardo Bare, states that "I can’t say definitively what might happen down the road, anything could happen, but Dishonored is resting for now," meaning that the series won't be having any new entries for the foreseeable future.
Instead, the plan is to look into a potentially new IP, with a focus on multiplayer. "Being able to incorporate more online sharing or multiplayer type stuff, we totally might do that. It’s interesting because, for a while, there was this push with a bunch of big publishers to force teams to include multiplayer modes. I feel this was super destructive because you end up with a team that’s made a really compelling single-player game, but they were forced to tack on this deathmatch mode or whatever."
Their most recent release, the standalone DLC; Dishonored: Death of the Outsider was a critical success, but not a commercial one. The game prior to that, Prey 2017, was also loved by fans and critics, but failed in terms of sales.
