We also see some of the Banished, Halo Infinite's main alien antagonists who were previously seen in Halo Wars 2. In the menu screen, we also see an item called 'Upgrades', suggesting you can make RPG-style improvements to Master Chief, which would be a first for the series. 343 Industries says the environment in Halo Infinite is 'several times larger than that of the last two Halo games combined' and we can see that there is a day and night cycle in play. This is a more open-world-looking Halo game, though, with an in-game map called the 'TacMap' that shows how you can explore different parts of this extra-sized Halo ring and tackle certain missions, each of which has its own difficult rating. It's reassuringly Halo-like, but leagues ahead in terms of presentation compared to the older games. There's a familiarity to the verdant environments, as well as iconic weapons on display as well as vehicles from the long-running series, including the Warthog.
Halo Infinite kicked off the show during Microsoft's Xbox Game Showcase event in July 2020, and as you can see from the trailer above, it's very reminiscent of Halo: Combat Evolved.
