Microsoft's E3 2018 presentation included a look at the next instalment in the Halo saga from 343 Industries. Titled Halo Infinite, the new game in the series is built on the Slipstream engine. Phil Spencer appeared on stage to say it would be Master Chief's "greatest adventure".

Although a trailer was shown, it was largely comprised of showcasing a number of environments, from a dessert to a forested area. At the very end of the trailer a number of soldiers are shown throwing down a flare, the camera then pulls out to show Master Chief's helmet in the corner of the screen.
