The new game is called Horizon Steel Frontiers, and Sony and the Korean video game company NCSoft are working on it together. Based on a more than 10-minute video we’ve seen featuring a mix of cinematic and pre-alpha gameplay footage as well as developer interviews, the game will focus strongly on fighting the Horizon series’ giant mechanical beasts and being able to do so with other people.
Sony and a PR company representing NCSoft didn’t immediately reply to a request for comment. The Verge initially spotted promotional art for Steel Frontiers on a website used to share game assets that media and influencers are approved to use. The art seems to have been posted early, perhaps ahead of an announcement at the G-Star 2025 event in Korea later tonight. The website also included a link to a Google Drive with open access that contained the video. According to that website, Steel Frontiers will be available on PC, iOS, and Android.
Footage from the video shows groups of players taking on beasts and navigating through lush natural environments and looming metal buildings you might be familiar with if you’ve played the Horizon games.
“Horizon Steel Frontiers is a full-fledged MMORPG that NCSoft has built specifically for mobile,” Jan-Bart van Beek, studio director at PlayStation’s Guerilla Games, says in the video. “With Steel Frontiers, you can step into this world anywhere, anytime. Players take on the role of machine hunters, chasing opportunity in a region called the Deathlands. This is inspired by Arizona and New Mexico. You’re sharing the frontier with thousands of other players, sometimes working together to take down machines and other times competing with rival tribes or fighting over resources, and that mix of cooperation and competition creates moments that you could never script.”
“The core concept of Horizon Steel Frontiers can be summed up in one phrase: the thrill of taking down colossal machines,” executive producer Sung-Gu Lee says in the video. “Hunting massive machines was one of the greatest appeals of the original Horizon series. And now, we’re expanding that experience into the world of MMORPGs.” Lee says there will be new mechanics for fighting the machines, like picking up dropped weapons from beasts and carrying them on a mount to use in later fights.
The video also highlights the game’s character customization features — in Steel Frontiers, instead of playing as Aloy, who has been the series protagonist so far, you’ll be able to make your own character.
There’s no release date listed in the video, but Lee says that the team is working to make the game available “as soon as possible.”
