Founded in 2000, Guerrilla Games is known for its FPS Killzone and action RPG Horizon IP. Sony acquired the Amsterdam studio just 1 year after Killzone released on PS2 in 2004, making them one of the oldest PlayStation developers.
On PS5, Guerrilla has only released Horizon Forbidden West in 2022, which sold 10+ million. They did work with other studios on 2023's Horizon Call of the Mountain, 2024's Lego Horizon Adventures, and a remake of Horizon Zero Dawn, but weren't the main developer.
Outside of collaborations and 2023's PS5 exclusive Burning Shores DLC for Forbidden West, Guerrilla had remained silent until 2026, when they announced Horizon Hunters Gathering. This live-service co-op Horizon title has its work cut out in order to win over the hardcore PS5 base that was hoping for Horizon 3.
The response to Horizon HG was extremely negative, with particular critique at its cartoony art style. If anything, Horizon Steel Frontiers, (a high-fidelity MMO for PC/phones by NC Soft) looks more like the live-service expected from Guerrilla, whereas HG looks like the phone title.
HG's first playtest is in late Feb, so it's not too long before players can get hands-on. However, this playtest must be executed perfectly. If gameplay and presentation falls short, the hardcore base won't only not evangelize the project, they'll crucify its reputation like they did Concord. HG will then have little chance of finding popularity with the more casual/live-service PS5 audience who might try an ok game, but not an uncool one.
Rumors suggest Guerrilla is also working on Horizon 3. Even if it's a PS6 title that's years away, it would do well for them to showcase it now. At the very least, a high-fidelity singleplayer Horizon will help take the heat off yet another live-service from one of Sony's premier PS Studios.
