Shortly after Halo Infinite was demonstrated on July 23 at the Xbox Series X games event, a rumor began circulating that the multiplayer portion wouldn’t be ready for launch this holiday. However, it was just that: a rumor. A 343 employee has cleared things up, and you’ll be able to play the whole game when it releases.
Replying to a thread on Twitter the following day, 343 community manager Brian Jarrard assured players that the multiplayer would indeed ship with the single-player campaign.
Nothing to see here folks, this is not true.

We only saw the campaign when the game was demonstrated during the Xbox Series X event, but Microsoft promised that multiplayer footage would be coming further down the line. That footage could include four-player split-screen support and footage of the grappling hook.
