There are a number of references to the 1982 film Blade Runner, both in the form of easter eggs as well as Spoiler:inspirations in the game's overall story:

• On top of the Mass Fusion Containment Shed building, there is a dead Raider wearing a duster and a dead Synth. The two bodies are posed similarly to Rick Deckard and Roy Batty in the "Tears in the Rain" scene from Blade Runner.
• The Power Noodles stand in the center of Diamond City, along with the Noodle-serving Protectron named Takahashi is likely inspired by the noodle stand and it's japanese-only speaking owner that Deckard eats at in Blade Runner.
• The town of Covenant requires a psychological "G.O.A.T Test" before it can allow newcomers in. Spoiler:The reasoning behind it is to tell who is a genuine human and who is actually a "Synth", very similar to the Voight-Kampf Test's done in Blade Runner, which is done to expose if the person being tested is a Replicant or not.
• Spoiler:A good portion of the game's plot/backstory involves the "Synths", who are inspired by the Replicants from Blade Runner, in the sense they can mimic humans almost perfectly and hide among them. There are even runaway Synths trying to find freedom, similar to the runaway Replicants Deckard is tasked to find in Blade Runner.
• Spoiler:Nick Valentine is arguably a product of inspiration from the movie, as he fits the "neo-noir" motif of Blade Runner.
