List of seven references in Halo

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

- Brian Jarrard, linking to this very page

"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. 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 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. In spite of the fact that the number seven is featured extensively in Bungie's work, it has generated an aura of apophenia. This cultural nuance can be compared to the 23 enigma.

Halo: Combat Evolved (and Halo: The Flood)
Page 68 of "The Flood" Novel by W.Dietz - He counted to three, then dashed from boulder to boulder. He leapfrogged uphill, still very much aware of the banshee at his back, but reasonably certain he'd given the aircraft the slip. There were no blips on his threat detector, until he topped the rise and paused to examine the terrain ahead. A telltale red dot popped onto his HUD. The Master Chief eased his way forward, waiting for the moment of contact. Then he saw movement as hunched bodies dashed from one scrap of cover to the next. There were four of them, including a blue-armored Elite. (3 seconds, 4 Contacts - 3+4=7)
