- Three Dog is referenced with a unique gun called Thre Dog and in its description directly references one of Three Dog's radio intros - "Because one barrel ain't enough, and two is too few". The original intro referenced is "Because one dog ain't enough, and two is too low, it's me, Three Dog!"
Cataclysm: Dark Days Ahead
Taking place in near-future New England, Cataclysm: Dark Days Ahead is a post-apocalyptic roguelike video game that features several references to the Fallout series.
- The "Necropolis" city type can be identified by its more organized layout compared to other cities and numerous radioactive craters, similar to the depiction of Necropolis and surrounding areas in Fallout.
- Known for their tendency to lunge at the player as their first attack, irradiated wanderers are former humans that suffered from mutations and madness, likely due to exposure to extreme doses of radiation. These are traits shared with feral ghouls as depicted in Fallout 3 onwards. Irradiated wanderers can only spawn in the city type "Necropolis," similar to how ghouls can only be found in Necropolis in Fallout.
- The Shishkebab, a weapon described as a "large blade with a fuel pipe on the side, and a small tank and igniter built into the insulated hilt" is a reference to the weapon of the same name that has appeared in the series since Fallout 3.
In Cyberpunk 2077, out in the Badlands, a wasteland-like region surrounding the main setting of Night City, a few corpses can be found around a circular dish with "101" on the front. An archived conversation nearby reveals that two of these individuals, Albert Cole and Gary Epps, were live-action roleplayers (LARPers), who were role-playing a post-apocalyptic scenario where they leave the safety of Bunker 101 for the first time since nuclear war. Albert Cole is a reference to the protagonist option of the same name. Gary Epps is a reference to the GURPs, the original gameplay system before SPECIAL. The scenario of the LARP, a search for a "hydroprocessor" to supply fresh water to the "bunker dwellers" also reflects the storyline of the first Fallout, obtaining a water chip for the vault dwellers of Vault 13. Bunker 101 is a reference to Vault 101.
