Killzone Returning as Guerrilla Games Working on New PlayStation Project

Sony may finally be bringing back Killzone after more than a decade, with reports suggesting an early remake or reboot.

PlayStation’s Killzone series may be returning after more than a decade in the wilderness. The series last appeared in 2013 with Killzone: Shadow Fall on PlayStation 4, with Guerrilla Games largely exclusively focused on the Horizon franchise after that. According to the report, a new Killzone project is in early development.

Killzone was one of Sony’s flagship first-person shooter franchises, even being marketed as a potential “Halo killer,” the insider said. The report says Sony plans to bring the series back, but an official announcement is still years away. The word has it that Killzone is back on Guerrilla Games’ projects list.

It seems the project is being worked on with the help of an outside studio instead of just by Guerrilla itself. It was not revealed which of the Killzone games would be restored. But the original 2004 game would seem like the most obvious choice for a remake or remaster

The insider said the Killzone project was supposed to be Guerrilla’s next big project after Horizon Hunters Gathering. But if recent whispers regarding the Horizon project are to be believed, Guerrilla has been forced to focus on getting it right and retooling it. This might push Killzone even further into the future.

Killzone’s revival might start with a visual makeover of an old favorite.

Insiders speculate that Horizon 3 could also be the next Killzone project but warn that plans could change owing to the early stages of creation. There have been rumors of a full-on reboot, but more credible sources mention a graphic boost or recreation of one of the earlier Killzone games and not a brand-new game.

One of the more interesting features of the study is the reported collaboration between Guerrilla and an external studio. PlayStation announced a co-development agreement in March 2025 with People Can Fly for a project called Delta, which is said to be based on existing PlayStation intellectual property.

This has not been proven, but the report claims that the material provided strongly shows that People Can Fly is involved in the new Killzone initiative. If genuine, the project would add another major production to People Can Fly’s already outstanding portfolio. However, the study warns plans may change, particularly while a game is still in the early phases of production.

Best of all, a new Killzone project is said to be in development. There is good reason for fans to be suspicious about the supposed return. Since the project is presumably still in its early stages of development, it can still be canceled. There’s no indication of an announcement coming soon in the story, so fans could be waiting years before knowing anything official.

The big question is whether Sony will truly let Killzone out.

That uncertainty is especially relevant given Sony’s history of projects that languished in development for years before being scrapped. So the rumored Killzone project is not a sure thing, and neither Sony nor Guerrilla has publicly acknowledged its existence yet. Another problem is the present condition of Guerrilla.

The studio has already put in a lot of work on Horizon Hunters Gathering, but allegedly it hasn’t gone down well with playtesters. The feedback has been so terrible that Guerrilla is now trying to change the game to preserve the project. The situation is significantly worse in Horizon 3.

However, recent sources have suggested that the next mainline Horizon game is still in its early phases of development, as it is being produced by a small team. If that’s the case, the next single-player Horizon could still be years away. The scenario has only amplified criticism of Sony and Guerrilla’s prior concentration on live-service games.

Guerrilla is presumably attempting to keep the Horizon multiplayer game alive and not scrapped. Another Horizon multiplayer project is also in development but is unlikely to be published on PlayStation 5. That makes Guerrilla’s present-day roster more complex and begs the question of whether the studio will return to its established single-player franchises.

Guerrilla’s live-service ambitions may have delayed its biggest single-player games.

There are lots of unknowns, but the possibility of a return for Killzone has PlayStation fans very excited. A remake or remaster could be an easy way for Sony to bring back one of their earlier games and introduce it to a new generation of fans. Sony's forgotten shooter franchise could get a revival with a Killzone reboot.

Hiring an outside studio can speed up the process more than an altogether new Guerrilla-developed game, particularly if the main goal is to update an existing game. But this is merely speculation, and there is no confirmed information about the development pace, scope, or release date of the project. Whatever the case, the alleged Killzone resurrection should be taken with a pinch of salt for now.

There’s been no official announcement; the name of the external development team isn’t set in stone, and the project might still change direction or be scrapped. But the notion of a Killzone revival is notable, given the franchise had gone more than ten years without a new major installment. If true, Sony might finally be ready to resuscitate one of the most famous dormant shooting games on PlayStation.
