So, we have a new Halo game coming out called Halo: Infinite. It's been a little tricky figuring out whether the title means the new Halo is a proper sequel or possible spinoff, but 343 Industries confirmed again that Infinite is the numbered Halo 6 sequel, just without the number.
"It is Halo 6," said Halo writer Jeff Easterling during a Halo Mixer stream [h/t GameSpot]. "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 is going on."
We've known that Halo: Infinite once again stars Master Chief in the lead role after Halo 5: Guardians opted to have two protagonists, one Master Chief the other Agent Locke. But then why ditch the 6 and call the game Halo: Infinite?
Unfortunately, 343 is keeping mum on the details. Perhaps Halo: Infinite is titled that way because it takes place several infinite iterations after Halo 5, but for the sake of continuity is still considered a sequel. Perhaps it was a way to call dibs on all the Halos from now and in perpetuity (too bad, I called Halo Infinite plus one).
Either way, details for Halo: Infinite are scarce following the brief reveal trailer from Microsoft's E3 2018 press conference. Halo: Infinite will run on a new Slipspace Engine and reportedly will take the series in new directions. We'll wait until we see more of Halo: Infinite to make any judgements on Master Chief's next move.
