Guerrilla Games is making a last-minute course correction on its upcoming co-op title set in the Horizon universe following poor playtest responses, according to a report from Bloomberg.

Initially conceived as a live service co-op action experience, Horizon Hunters Gathering tasked players with teaming up as stylized heroes to battle mechanical beasts. Internal feedback across three separate playtests earlier this year proved largely negative, with one test session notably struggling to gain traction while competing directly against a Marathon server slam event.

Rather than canceling the project outright, Sony management has granted the studio several months to rework the concept into a smaller, narrative-focused cooperative game. Sources familiar with the matter revealed that Sony notified the development team that they must present an impressive updated vision during a critical milestone review scheduled for December.

Failing to meet executive expectations in December could land Horizon Hunters Gathering alongside a growing list of abandoned live service titles. Sony has canceled several multiplayer spinoffs in recent years, scrapping high-profile projects tied to major franchises like God of War, The Last of Us, and Spider-Man before they reached public release.

Internal staffing updates indicate that a significant portion of the developers previously assigned to Horizon Hunters Gathering have already been reassigned. Meanwhile, a smaller dedicated team within Guerrilla Games continues early production on the next mainline single-player Horizon entry.
