* While not nearly to the extent of ''Halo'' itself, Rooster Teeth has frequently played {{Homage}} to Bungie's love of [[ArcNumber the number seven]] - Sister's claimed that she's had seven abortions, the Red Zealot of the Battle Creek Zealots claimed that Caboose [[TheAntiChrist "the [=Anti-Flag=]"]] would rule over them for seven years, the Meta captured seven different [=A.I.=] fragments before their defeat in ''Reconstruction'', Grif is on the receiving end of seven different {{Groin Attack}}s from Tex during "This One Goes To Eleven," and both [=Alpha-Church=] and [=Epsilon-Church=] only each lived for seven years InUniverse before they were destroyed.

* ''Revelation'' has Sarge mention how the pistol "isn't quite as effective as it used to be." This is meant to be a reference to how the pistol was [[GameBreaker absurdly]] [[OneHitKill overpowered]] in ''VideoGame/HaloCombatEvolved''. Furthermore, Sarge also notes that the older models of rocket launchers (which are found in the Freelancer Offsite Storage Facility) have heat-seeking, which is an allusion to how the rocket launchers in the first two ''Halo'' games also had that feature in gameplay. In fact, the [=UI=] for the original rocket launchers is briefly seen when Simmons fires it at Tex.

* The lessons on [=A.I.=] theory shown in the Project Freelancer flashbacks during Season 10 are accurate to how the [=life-cycle=] of [=A.I.s=] played out in the ''VideoGame/{{Marathon}}'' games.
* [[{{MacGuffin}} The "sarcophagus"]] that Project Freelancer spends most of Season 9 hunting for is eventually revealed to contain an Engineer/Huragok, which proves to be vital in cultivating the Freelancer [=A.I.s.=]

* According to "The Federal Army of Chorus", Donut's safeword is "Chrysanthemum." In the canon of the ''Halo'' games, Project [=CHRYSANTHEMUM=] was the name for the bio-augmentation process used in the development of [[SuperSoldier the SPARTAN-IIIs]].
* In "Fed vs. New," Locus claims that being a soldier and a human are two completely different things, echoing a similar sentiment made by [=John-117=] in the epilogue to ''VideoGame/Halo4''.

* According to ''Red vs. Blue: The Ultimate Fan Guide'', Wash completed his basic training in the [=Leonis-Minoris=] system before becoming an Army Corporal in the [=UNSC=] and eventually joining Project Freelancer. The [=Leonis-Minoris=] system is an actual star system in ''Halo'' canon, and it was all but destroyed by the Covenant in 2537.

* In a sense, [[OurGodsAreGreater the Cosmic Powers]] introduced in ''The Shisno Paradox'' can be seen as [=RvB's=] interpretation of [[{{Precursors}} the Forerunners,]] in that they're immensely powerful ancient entities worshiped as gods [[spoiler:that overthrew their own creator, are heavily reliant/based-on sophisticated [=A.I.s,=] and are generally far less divine than they may first seem]].

* The number "040103" can be seen at the bottom left hand corner of the film reel in "Fight the Good Fight". This is an allusion to how the first episode of ''Red vs. Blue'' aired on April [=1st=], 2003.

** When Dylan lists random acronyms to trick her way into the crime scene, she states they're expecting an "RT double-A" in the next few minutes. ''WebAnimation/RoosterTeethAnimatedAdventures'' (or [=RTAA=]) is another show produced by Rooster Teeth that regularly features the creators of [=RvB=].

** In "Battlescars," Temple taunts Carolina by claiming the longest record for surviving in [=armor-lock=] is 8 days and 11 hours. Season '''8''', Episode '''11''' was the first episode to introduce the concept of [=armor-lock.=]

* The first place Caboose visits while time-traveling during ''The Shisno Paradox'' is [[VideoGame/HaloReach Reach]]. This is a nod to the Season 9 [=RvB PSA=] "How I Spent My Summer Vacation," where Caboose stumbled through the singleplayer campaign of ''Halo: Reach''.

* Genkins TheTrickster (a member of the Cosmic Powers) is one massive example of this trope in action - His name, green armor, and [=CQB=] helmet all reference Jenkins, a Blue Team member of questionable canonicity that was first introduced in the "Ruby Slippers" [[MultipleEndings Alternate Ending]] to [[WebAnimation/RedVsBlueTheBloodGulchChronicles season 5]] finale "Why Were We Here?". [[spoiler:Post-TimeCrash, he replaces Church, so he may well actually ''be'' Jenkins.]]
* The official episode description for the episode "Finally" from ''Singularity'' is "Caboose's Guide to [=Re-Zipping=] Time," which is a reference to both the (possibly) non-canon [[WebAnimation/RedVsBlueSeason14 Season 14]] episode "Caboose's Guide to Making Friends" and non-canon PSA "Caboose's Guide to Finding Your Home".

* In "The End", Tucker dismissively tells Hargrove that the Reds and Blues will "wing" their survival aboard the ''Staff of Charon''. This is likely an allusion to Tucker saying the same thing to Kimball in the [=non-canon=] Season 12 Teaser Trailer.

* The official episode description for the episode "Finally" from ''Singularity'' is "Caboose's Guide to [=Re-Zipping=] Time," which is a reference to both the (possibly) [=non-canon=] [[WebAnimation/RedVsBlueSeason14 Season 14]] episode "Caboose's Guide to Making Friends" and [=non-canon=] [=PSA=] "Caboose's Guide to Finding Your Home".
