  • An Unlikely Alliance: The game is a surprise collaboration between Horizon’s creators, Guerrilla, and Korean MMO powerhouse NCSOFT, known for titles like Lineage and Guild Wars.
  • Play Anywhere: Horizon Steel Frontiers is being developed as a cross-platform title for both PC and mobile devices, aiming to bring large-scale battles to a massive audience.
  • First Look Revealed: The game was unveiled at Korea’s G-Star 2025 conference with a debut trailer showcasing its world and mechanical creatures.

A New Frontier for a Beloved Universe

In a move that has the gaming community buzzing, renowned Korean developer NCSOFT has officially pulled back the curtain on Horizon Steel Frontiers, a new MMORPG set in the post-apocalyptic world made famous by Aloy. The surprise announcement came during Korea’s premier gaming conference, G-Star 2025, revealing a major strategic partnership with Sony Interactive Entertainment (SIE) and Guerrilla, the masterminds behind the original Horizon series.

This new title promises to merge the signature machine-hunting action that fans love with the deep, large-scale combat systems that have made NCSOFT a titan of the MMO genre. Players will explore the Deadlands, a new region in the Horizon universe, with what developers are calling extensive player freedom and deeply customizable combat.

East Meets West: A Landmark Collaboration

What makes this announcement so significant is the fusion of two very different development philosophies. Guerrilla is celebrated for its narrative-driven, single-player masterpieces, while NCSOFT dominates the world of persistent online multiplayer games.

In a developer commentary video, Jan-Bart Van Beek, Studio Director at Guerrilla, expressed his excitement about the collaboration. He was joined by NC CEO Taekjin Kim and Executive Producer Sunggu Lee, who shared their vision for translating the core Horizon experience into a massive online world. This partnership signals a bold new direction for the franchise, but one that leverages the strengths of two industry leaders.

What to Expect from Steel Frontiers

The debut trailer, launched alongside a new official brand website, provided the first glimpse into this expanded world. It highlighted vast landscapes, new and familiar mechanical creatures, and the kind of large-scale battles that are only possible in an MMO. The game is being built to run on both PC (via NCSOFT's PURPLE platform) and mobile, indicating a major push for accessibility and a global player base.

While further details remain under wraps, the initial reveal confirms that Horizon Steel Frontiers is not just a spin-off but a major new pillar for the franchise. The focus is on translating the thrill of the hunt into a shared online experience where legions of players can fight together against colossal machines.
