"Some of you may be wondering - "What's up with this unhealthy obsession with the number 7?" This page offers some insights."

"Cause that's the best number. It's like rock. Nothing beats rock or 7."

— Michael Wu

Bungie Studios has long enjoyed using the number Seven (7) in its games in many prominent ways. Ensemble Studios and authors also have certain obvious seven references in their works about Halo. While almost anything can be made into a reference to something with effort or construed accidentally through pareidolia, the following attempts to list the intentional references Bungie placed into Halo for the fans to find. As such, not all of these references may be fully accurate, and many of them may be proven to be false at any time. Bungie's obsession with with the number seven may be attributed to (or be a determining factor) why John-117 is considered lucky, as 7 is considered a lucky number.

117

117 is Master Chief's SPARTAN tag number, but there is more than meets the eye when it comes to this number, including many religious and historical references.

• 1x1x7=7
• Dr Halsey points out that there is only one hour and 17 minutes (1:17) left before the portal closes.
• Both the trailers for Halo 3: ODST and Halo: Reach are 1:17. This may alternatively be a reference to 7, as 1:17 in seconds is 77.
• During the Battle of Alpha Aurigae, Vice Admiral Preston J. Cole had one hundred seventeen (117) UNSC ships at his command.

Site 117

Alternatively, others believe the number to be a reference to "Site 117", an archaeological site containing the first evidence of a human battle. The site is near Jebel Sahaba, Nubia and dates from between 12,000-10,000 BC. The site contains 59 human remains of men, women and children who were clearly killed with primitive hunting implements.

117 and 7

It is conjectured that the numbering system for Halo installations' Monitors is, where $n$ is the number of their installation, $7^{n-1}$. With this in mind, it is reasonable to assume that the number of the Monitor of Installation 07 is $7^{6}=117649$. As well as including the number 117 when it is written in base-10 (decimal), it also includes 649. $9+4-6=7$.

The number 819 appears numerous times in the Marathon series. $819/7=117$. This tradition started in Marathon Infinity, with two secret terminals on the first and last levels of campaign mode. At first sight, these terminals seemed to contain nonsense. However, if the data from both terminals was copied into ResEdit (the classic Mac OS's hexadecimal editor), converted into text format, then expanded twice with Stuffit Expander, a map file would be revealed which could then be loaded in Infinity. The 819 was a reference to Hamish Sinclair, a prominent member of the community at marathon.bungie.org (the sister site of halo.bungie.org) as if one assigned letters to numbers sequentially ($a=1,b=2,c=3\ldots$) then Sinclair's initials, H.S., would be 8.19.

Marathon

• The music for Marathon 2: Durandal and Marathon Infinity was composed and produced by an external music group called 'Power of Seven'. (Similarly, Marathon 2: Durandal also has an achievement with the same name.)

• In the original Marathon, the barrels all have a backwards 7 in the serial number.

117 Trivia

• In Halo 3, the game won't let you input the I.D. tag "I (upper-case i)-17", "l (lower-case L)-17", or "T-17" saying that these numbers are already reserved by the UNSC.

• In Halo: The Flood, Yayap tells 'Zamamee that Master Chief must go through corridor E-117.
• The Halo: Reach Video Game Awards Trailer takes 117 MB of memory to download from the Xbox Live Marketplace.
• It is likely that one reason Bungie chose 7 as their "number of obsession" is because 7 is often seen as a lucky number which coincides with the idea that the Master Chief's defining trait is that he is lucky.
• 117 is the hotline for the PNP, another one of the "hidden" references to the Philippines, notable for being a westernized Southeast-Asian country.
• Halo: Reach is released 117 days after the Beta.
