Before the studio became famous for working on 2017's award-winning action RPG title, Horizon: Zero Dawn, and its upcoming sequel, Guerilla Games had a series of single-player shooters with a multiplayer component in the Killzone series. The FPS titles were popular and successful enough to see 4 mainline games and 2 spin-offs. However, this would all end after 2013's Killzone: Shadowfall. Afterward, Guerilla applied its penchant for making graphically beautiful games for PlayStation consoles to an exclusively single-player affair.
With that said, this could all be changing soon. A slew of job listings suggests that Guerilla intends to go back on working on multiplayer titles soon.
Is Guerilla working on a new Killzone game?
Several job postings on its official website suggest that the studio is hiring for a game with a big multiplayer focus. It's worth noting that none of the listings give much info about what kind of project the studio is hiring for. However, there's enough evidence to suggest that Guerilla is going back to multiplayer games. This is interesting since Sony was criticized earlier this year for focusing too much on single-player games.
