It’s been known for a while now that Texas-based support studio Certain Affinity is working on a “new and exciting” mode for Halo Infinite, and now noted Microsoft insider Jez Corden has seemingly spilled the beans on the latest episode of The Xbox Two podcast. There has already been plenty of speculation that Certain Affinity’s new mode may be some form of battle royale, and apparently, Corden has received confirmation of that. This new Halo battle royale won’t be some hastily assembled toss-off either, as Corden claims it’s been in development for at least two years, and is similar in scale and ambition to other battle royale games like Call of Duty Warzone.

I have information that suggests it's battle royale. That it's some form of battle royale. I don't know if it's going to be specifically a clone of PUBG and stuff like that, but this is going to be a huge mode. This mode has been in development for over two years at Certain Affinity and it's a big deal. It's a huge investment and they've been working on it for a really long time. This isn't just [...] a few game modes here and there, this is a big [Call of Duty] Warzone-scale undertaking. It's basically like a separate game.
