Guerrilla in 2026: Horizon Goes Co-op, Goes Korean and Waits for Aloy
The Amsterdam studio behind Killzone and Horizon is now juggling a three-player co-op game, an MMO with NCSOFT and a long-awaited sequel. Here is what is confirmed.
On January 1, 2000, three small Dutch studios merged into one company called Lost Boys Games. It made handheld games for hire, with titles like Rhino Rumble and Dizzy's Candy Quest. Twenty-six years later, renamed Guerrilla, it has three versions of one of PlayStation's biggest worlds in the works, and one of them is being co-developed in Korea.
In February 2026, Guerrilla revealed Horizon Hunters Gathering, an online co-op game for PS5 and PC in which teams of three players hunt machines together. Alongside it, the Horizon Steel Frontiers MMO being co-developed with Korea's NCSOFT is listed for 2027 on PC and mobile. And Aloy's next solo adventure, the sequel to Horizon Forbidden West, remains officially unannounced.
Horizon, together
Horizon Hunters Gathering was announced on February 5, 2026. What we know:
- Players: online co-op, built around squads of three Hunters.
- Platforms: PS5 and PC.
- Modes seen so far: Machine Incursion, a high-intensity mission in which machines pour out of underground gateways behind a powerful boss, and Cauldron Descent, a longer multi-stage trial through shifting rooms with hidden doors and rewards.
- Testing: a small-scale closed playtest began at the end of February 2026, through the PlayStation Beta programme, followed by a second test in May.
There is no release date yet. The idea is easy to understand: Horizon's best moments have always been the fights with huge robotic animals, and this game builds entirely around them.
The Korean connection
Horizon Steel Frontiers is the most unusual project in the family. It is a Horizon MMORPG co-developed with NCSOFT, the Korean company behind Lineage and AION, together with PlayStation's external development group, XDev. It is planned for Windows, Android and iOS in 2027. Few further details have been confirmed.
For PlayStation, it is a striking move: one of its most valuable worlds handed to a partner that has spent nearly three decades making online role-playing games. For NCSOFT, it is a chance to build on a global brand rather than its own Korean-born series.
From Killzone to Horizon
Guerrilla made its name with Killzone (2004), a PS2 shooter that sold over a million copies. Sony bought the whole studio in December 2005, and three more Killzone games followed, ending with Shadow Fall (2013) on PS4.
Then the studio took a huge risk. Horizon Zero Dawn (2017) swapped grey sci-fi corridors for a lush post-apocalyptic world, and it sold 10 million copies by February 2019. Horizon Forbidden West (2022) and its Burning Shores expansion (2023) continued the story; the Complete Edition sits at 89 on OpenCritic.
The studio today
Guerrilla is based in Amsterdam and had 385 employees in 2025. It is led by Jan-Bart van Beek alongside studio directors Joel Eschler and Hella Schmidt, after co-head Angie Smets moved to a PlayStation-wide role in 2023. Technical director Michiel van der Leeuw now focuses on Decima, which remains one of the most respected engines in the industry.
What's next
Expect Horizon Hunters Gathering to be the next Guerrilla game you can actually play, with more playtests likely before a launch date. Steel Frontiers is NCSOFT's to show. And the big question, a third Aloy adventure, has been rumoured since 2023 but has not been announced.
In the meantime, Horizon Forbidden West Complete Edition on PS5 and PC is the best place to start, or to return.
