Besides Horizon: Forbidden West Guerilla Games is apparently working on another unannounced game. Fans are hoping for a new title. Killzone or SOCOM.
The clue comes from the LinkedIn profile of Simon Larouche, Game Director at Guerrilla Games, who has apparently been working on this project since 2018. Previously, Larouche had worked on high-profile titles such as... Far Cry Instincts, Rainbow Six: Patriots, Splinter Cell: Blacklist, Watch_Dogs 2 or Killzone 2 He contributed to the project. So, there are definitely ambitions for another shooter.
It is not unusual for Guerilla to have sent another project into production now that Horizon forbidden west It's practically ready for release. The fact that it's been in development for a good three years suggests that the release of the project isn't too far off.
The last Killzone It was released at the launch of the PS4 in 2013. Since then, the series has been dormant, and Guerrilla Games turned to a completely new genre and the open-world game concept with Horizon. Whether that KillzoneWhether the franchise will get another chance remains to be seen. Generally speaking, Sony currently lacks shooters, even though they own several brands that would be welcome revivals, including this one. a new SOCOM, which has been suspected for some time.

I think we'll probably get a new Socom or something else.
Sony will postpone Killzone for now due to the "failure" of the last installment.
Hope killzone in the above trilogy timeline
