Castle

 * In the third-season episode "Last Call", Castle (Nathan Fillion - Reynolds & Edward Buck) and Beckett interview an internet millionaire at his apartment. In the background several guests are playing Halo: Reach. The screen is briefly viewed, and in-game sound effects can be heard throughout the scene. Careful listeners can discern the sounds of armor lock, M9 frag grenades, MA37 assault rifles, M395 DMRs and s.
 * In the sixth-season opener, "Valkyrie", Detective Esposito (Jon Huertas - Trooper 1 in Halo: Reach) hassles Castle for being away, saying he's missed "three Halo nights."

Dexter

 * In the third-season episode Go Your Own Way, while camping out in Miguel's office, Dexter entertains himself playing Halo 3. This is a joke where he narrates about setting up to kill people, something we imagine he's preparing for Miguel, but it turns out to be a game. Oddly, the game is played on the computer, which while not impossible, is unlikely to have been set up in such a way as the game itself has no computer port. In addition the sound effects are different. Oddly enough the stats were actually recorded on Bungie.net. The game was played Rat's Nest, with Dexter playing as someone called Badpunisher33, against someone called nmagoose.


 * In the fifth-season episode First Blood, Detective Debra Morgan and Office Cira Manzon stop their vehicle by a wall containing numerous posters, many featuring the cover art for Halo 3: ODST. Later, it's found that underneath some of these posters are signs relating to the Venezuelan gang.

Unlike its Halo counterpart, however, it transmits itself through water, from which it supposedly gets it name.
 * In The Waters of Wars, a human settler on Mars conjectures that the Philippines would likely be the next country to colonize Mars. Perhaps coincidentally, several locations on Mars in the Halo universe are named after places in the Philippines.

The Expanse
In the finale of Season 6, titled Babylon's Ashes, a joint force of United Nations and Martian Marines are deployed into a battle. During the sequence, a readout listing all of the Marines' names can be seen, with almost all of the names consisting of references to famous characters from many other science fiction franchises including Mass Effect, Alien, Starship Troopers, Titanfall, Bladerunner and several others. Included in the list is a Marine who goes by the name of "E. Buck" - a reference to Edward Buck.

During the concept production process for the MCRN Donnager in Season 1, a piece of Halo 3 concept art by Isaac Hannaford was used for visual reference for the art department alongside artwork of the Birmingham from Titanfall.

As soon as they begin to fight with the Covenant, John encounters Sergeant John Forge, who has been mortally wounded. As Forge claims that he is dying, John immediately states that he cannot show his physical features as a dying request. Later, John encounters Sergeant Johnson. Johnson is aggravated by John's poor combat performance, lack of a weapon, and the fact that he cannot understand any of John's use of facial expressions.

 * One sketch features Adam and Jamie from Mythbusters dressed up as Ghostbusters. Their dematerializer's are Assault Rifles connected to back backs.

Scrubs
In the second episode of season seven, Turk and Carla are attempting to complete a video game at the hospital.

While doing so, she mentions blowing Sheldon's head off and watching it "fly away"; such dismemberment is not present in the game, aside from the Flood.
