Halo Infinite likely set on Installation 07, may revive the Flood

Earlier this week Microsoft debuted the long-awaited next entry in its Halo first-person shooter franchise, titled Halo Infinite. Almost three years since the launch of Halo 5: Guardians, the title is set to continue the "reclaimer saga," diving deeper into the Master Chief's relationship with Cortana.

Although the initial reveal sparked more questions than answers, one keen-eyed Reddit user may have unearthed more surrounding the game's setting. Breaking down morse code broadcasting on a walkie-talkie, the trailer appears to contain a hidden message, "SOS ZETA HALO GRD." This likely refers to "Zeta Halo" – one of seven remaining Halo ringworld in existing lore, named Installation 07. This installation has been mentioned extensively through the books, but is yet to make be featured in the games themselves.

Diving into its background, Installation 07 appears to house an Earth-like ecosystem, with rich flora and fauna on its surface. As highlighted in the trailer, the world is packed with grasslands, forests, deserts, and an abundance of animals similar to those on Earth. The "Halo: Hunters in the Dark" novel even makes reference to "deer-like animals," which are likely those featured in Halo Infinite's opening trailer.

Installation 07 also appears to feature heavy ties to Forerunner heritage, with Flood and infected Forerunners supposedly left on the ring when most life was relocated to the Ark. The location is home to proto-Graveminds and other Flood organisms – potentially laying foundations for their revival after Halo 3. Whether or not they survived the original activation of the rings by the Forerunners remains unclear, though we'll hear more leading up to launch.

Deeper dives into Installation 07 and its history can be found throughout Halo novels, though roundups of most specifics can be found online. Although not confirmed by Microsoft, the ringworld is expected to feature in some capacity for Halo Infinite. What are your opinions on the game so far? Let us know your thoughts in the comments.

  • I hope we see Blind Wolves in Halo Infinite.
  • I was happy and disapointed at the same time. How this could be Halo 6 ? There absolutely no détails in this trailer showing any clue concerning the end of Halo 5. I want to know how this story ends, not start a new one without ending the last trilogy.
  • It was just a teaser...it likely has little canonical significance (see the Halo 5 teaser of chief in a cloak in a desert)
    I am certain it will be a direct continuation of 5, based off what they said at E3.
    Edit: This is directly from 343's post on Waypoint "In Halo Infinite, the game will focus on the Master Chief and continue his saga after the events of Halo 5."
  • Is Installation 07 the one in Primordium? I haven't read it in years, but I think it is? If so, this game will be very interesting! I can't wait to see more
  • If that is indeed true, than I think we 'finally' might be in for a treat with the story. I am not sure why Bungie decided to change all the known cannon with Reach, but I think 343 has been trying to expand on the 'known' Halo universe (from the books). My vague recolection of installation 07, is that indeed it is the 'rogue' ring that was stollen by Medicant Bias (the rampent AI from from the forerunner trilogy, and the same ring that was the entire story of Primordium). I have to go back and check, but it might also be the same installation that the Swords of Sanghelios (the elites that were helping Spartan Locke and company in Halo 5)went to and eradicated a 'flood' outbreak. Thus, fully operational ring, flood outbreaks, the events of Halo Wars 2 on the Arc, makes for a potential clash between UNSC, Elites, rogue Brutes, flood, and Cortana a wonderful climax to Halo 4-5-6.
  • Bungie had to hire Eric Nyland to make Halsey's journal as a bundled bonus for certain Reach bundles to "fix" the canon so Halo Reach fit with established canon. And yes. Zeta Halo, Installation 07, was the one in Primordium and the only remaining Halo from the original array.
  • The flood was already revived in Halo Wars 2, which takes place between Halo 5 and Infinite.
  • Yes on the Ark.
  • I just hope they do a lot more back story this time. Halo 4 and 5 made sense if you read the books but if you didn't there was a layer of depth and explanation that wasn't there. especially halo 5 blue team just magically shows up but if you didn't know who blue team was and their significance then I could see a lot of confusion.
  • Yeah, I haven't read any of the books, so a lot of Halo 5 made literally no sense, like how Buck was suddenly a Spartan.
  • Yeah, I didn't have a clue who they were, but I just kind of accepted they were there for some reason...
  • What I want to know is if 343 Guilty Spark is going to possibly make an appearance? I can't remember which book, but at the end he is recovered by a UNSC ship and he takes over the ship. How is that tidbit going to tie in. Through this game or in another book.?
  • Halo Silentium...and he apparently knows the location of the Librarian who isn't dead (at least that is the impression they left us with).
  • Any idea or hint of a release date yet?
  • 2020 is the rumour, possibly to be cross gen with the new Xbox, "Scarlett".
