[[Bungie]] has long enjoyed using the number '''seven''' ('''7''') in its games in many prominent ways.<ref>[http://marathon.bungie.org/story/seven.html '''Marathon.Bungie.Org''': ''The Number Seven'']</ref> [[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 constructed accidentally through [[wikipedia:pareidolia|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 the number seven may be attributed to 7 being considered a lucky number in Western culture. In spite of the fact that the number seven is featured extensively in Bungie's work, it has generated an aura of [[wikipedia:apophenia|apophenia]]. This cultural nuance can be compared to the [[wikipedia:23 enigma|23 enigma]].


[[Bungie Studios]] has long enjoyed using the number '''Seven (7)''' in its games in as many ways as possible. [[Ensemble Studios]] and authors also have many seven references in their works about ''Halo''. Therefore, in many of their games, this eccentric idea has caused a wild hunt for as many references to the number as possible (even if some are unintentional).
After [[343 Industries]] took over the ''Halo'' franchise in 2011, references to 7 have continued, possibly as a homage to Bungie.

"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[1]

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

Bungie has long enjoyed using the number seven (7) in its games in many prominent ways.[2] 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 constructed 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 the number seven may be attributed to 7 being considered a lucky number in Western culture. 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.

After 343 Industries took over the Halo franchise in 2011, references to 7 have continued, possibly as a homage to Bungie.
