History ShoutOut / Halo

* The final chapter title in ''Reach'', in Lone Wolf, is "There'll be another time", something said by Han Solo to Chewbacca during the iconic carboinate scene in ''Film/TheEmpireStrikesBack''.

* "We're screwed, we're screwed man!"("We're fucked, we're totally fucked!", which got changed to "screwed" in the TV version), and of course, "Game over man, game over!"

* The Mantis MiniMecha in ''Halo 4'' is an obvious reference to the titular ''Franchise/MetalGear''. On entering the vehicle, the OST will change to synth-like music straight out of ''VideoGame/MetalGearSolid''.

* Halo Anniversary gives us the Bandana Skull that gives you infinite ammo. [[Franchise/MetalGear Just like the bandana from another series.]]

* The protagonist of ''VideoGame/HaloReach'' is designated "Noble Six", a reference to Alfred Tennyson's "The Charge of the Light Brigade", which refers to the titular brigade as the "Noble six hundred". It's also {{Foreshadowing}}, of course.

* The principal actors of the ''Halo'' inspired machinima ''Machinima/RedVsBlue'' also appear in ''Halo 3'', delivering an in-character exchange, the participants and contents of which vary by difficulty level. They return in ''4'' for the radio snippets found in the Spartan Ops mode.

* Halo's Wolverine rocket-launching tank is basically the same as the Wolverine from ''GIJoe''.

** Most obviously, it's hard to look at anything Flood related and not think of the Xenomorphs. Both have small, roughly chicken-sized larval forms (Flood infection forms and face-huggers respectively) who scurry around looking for a host to jump and attach themselves to. Both burrow into said hosts and essentially puppet them, transforming the host into various forms of beasts that are distinct from each other but all follow the same general design trend (note the various Flood infection forms whether they be human, Brute, Grunt, etc. and compare them to the various forms of [[https://en.wikipedia.org/wiki/Alien_(creature_in_Alien_franchise)#Alternative_forms Xenomorph]]). Both are hive-based and don't seem to be individually sapient. Both rely on [[ZergRush numbers]] and their superhuman physiology to carry them in battle. And both are found as a few small samples on an abandoned craft, remnants of an infestation that wiped out an entire advanced {{Precursor}} race, only to get brought back into being unwittingly by humans, allowing them to spread rapidly from there.

* The first game has several ''{{Franchise/Alien}}'' references, including the calico cat Jonesy, "I have a bad feeling about this (drop)", "We're screwed, we're screwed man!"("We're fucked, we're totally fucked!", which got changed to "screwed" in the TV version), and of course, "Game over man, game over!" And of course, it's hard to look at anything Flood related and not think of the Xenomorphs.

* One of the stories in the ''Halo: Fractures'' short story anthology features a shout-out to the hosts of the Website/YouTube channel WebVideo/OutsideXbox.

* In a ShoutOut to the series, Microsoft named their voice assistant app in Windows Phone 8.1 and Windows 10 after Cortana. Originally it was just a codename during 8.1's development, but after word got out, fans campaigned for it to be kept. Not only did they do just that, they brought in Jen Taylor to provide the voice.

* ''VideoGame/{{Halo 3}}'' has a number of cameos from Sci-fi television, including "Sergeant Reynolds" (voiced by Creator/NathanFillion, who at one point gets to deliver the beginning of the quote on BigDamnHeroes) and a Marine voiced by Creator/AdamBaldwin shouting "Say hello to Vera!", along with Alan Tudyk delivering a very Wash-like speech "Tank beats ''everything''". Katee Sakhoff appears from ''Series/{{Battlestar Galactica|2003}}'' to lend a voice to some of the female marines.
