Halo Infinite will usher the series towards open-ended gameplay, as glimpsed in the gameplay showcased a few days ago. As part of a recent press Q&A session we were a part of, 343 Industries Studio Head Chris Lee described the approach as taking Halo Combat Evolved, knocking walls down, and giving players complete freedom to explore the ringworld.

The campaign in Halo Infinite is the most ambitious campaign we have ever created in a Halo game. It's this open, expansive experience for players, and it's several times larger than our last two campaigns put together. I think the way to think about it is this is Halo's take on open gameplay and what kind of providing the player with unprecedented levels of freedom can feel like. We really wanted to capture that moment of players being able to kind of feel what it would be like to be on a foreigner ring and unlock secrets and kind of new equipment or upgrades along the way as they're playing through the campaign. And I have one way to kind of give them more concrete examples when you're looking at the demo. We showed and you're on the elevator looking out over that vista. There's a ton of the ring that you can see there and that is just part of the space that players will be able to explore and where Master Chief's story will take you throughout our campaign experience.
