Halo Infinite was reportedly set to receive campaign DLC at one point, and it was in R&D phase prior to 343 Industries getting hit with layoffs.
According to Twitter user Mr_Rebs_, who is known for sharing gaming related leaks, developer 343 Infinite was hit by layoffs in January, 2023, particularly the campaign team, which had been involved in the development of DLC at the time.
According to the leaker, the Lead Environment Artist at 343 Industries, Ryan Roth, may have been part of the layoffs, as he had received job recommendations from other 343 employees in January. The developer has listed working on R&D for an unannounced project as well as campaign content for Halo Infinite as the Lead Campaign World Artist. He took this position at the studio in January, 2022.
It was previously reported that 343 Industries had no campaign DLC in active development for Halo Infinite. This is corroborated by the above information, which suggests that the project never moved beyond the R&D phase.
According to both Jason Schreier and Jez Corden, prior rumors regarding Halo Infinite campaign DLC getting scrapped are false because such content didn’t exist in the first place. Developer 343 Industries is currently focused on the multiplayer side of things, and no single-player DLC for Halo Infinite is in active development.
Prior rumors had stated that, before Bonnie Ross had quit, Joseph Staten was preparing to ship multiple contained Campaign DLC with a small team of developers in order to expand Halo Infinite’s narrative over the course of months or even years. According to the false rumor, this plan was halted when Pierre Hintze and the new key roles came in after Ross’ departure.
The rumor further stated that they ultimately saw a lot of complexity in developing new content for the campaign and deemed it unworthy of pursuing due to it not being profitable enough for sustainability. According to the false rumor, the development team decided to completely halt campaign DLC and focus on the multiplayer for the time being.
