Guerilla Games is about to expand the Horizon universe next year with Horizon Call of the Mountain in February and Horizon Forbidden West: Burning Shores in April. In addition to this, Netflix is in the middle of developing a live-action adaptation of the franchise, which will reportedly explore the years that led to the catastrophic events that created the game's world. But, it appears this isn't the only Horizon-related projects fans can look forward to, as the studio is working on a "separate Online Project" set in the same universe.

Guerilla confirmed the news before the weekend on Twitter when it shared an open call for at least three dozen developers to join the studio's "Single-Player (SP), Online Projects (OP), and External Project (EP) teams."

Earlier rumors suggested the existence of a multiplayer Horizon title, and Guerilla's post all but confirms this. But, while Sony Interactive Entertainment and Guerilla refuse to explain what its actual plans are for the Horizon MMO, the job listings do give us a glimpse of what to expect. For example, the narrative designer will come up with a "deep, complex story" while the game writer will have to think about "compelling ideas for quests, factions, and backstories." Finally, the hired lead combat designer will need to draw up enemies with an emphasis on "exciting combat with cooperative elements."
