As 343 Industries just confirmed, there won't be a "real" Halo 6, but Halo Infinite will (technically) take its place. In other words, Halo Infinite is our Halo 6. Clear now? Good!
It's not surprising at all, to be honest, and most of us expected Infinite to continue the story of Halo 5: Guardians. During a special Mixer broadcast, Jeff Easterling confirmed the following: "It is Halo 6. You should just consider it Halo 6. Don't think of it as a weird prequel kind of thing. It's the next story. It's the next chapter in what's going on". So, there it is, fair and square!
343 Industries is working on Halo Infinite along with SkyBox Lab and they even developed a brand new engine to power the game. It just gets to show you how serious they really are.
We don't know when the game is coming out but we are hyped as hell! Don't make us disappointed guys!
