In addition to normal detective activities such as examining crime scenes and gathering testimonies, Date and Aiba are able to dive into a person's dream world, or Somnium, in order to uncover the truth a subject's conscious self can't or won't reveal.
Date's newest investigation focuses on the death of a woman named Shoko Nadami, whose corpse was discovered with her left eye missing.
As more bodies are discovered, each missing the left eye, it becomes apparent that they are the work of a serial killer dubbed the New Cyclops Killer.
The more Date digs into the increasingly-complex case, the more it seems that it may have some connection to his missing memories and the Original Cyclops Serial Killings of six years ago...
Gameplay is divided into real world and Somnium segments.
In the real world, Date examines crime scenes and talks to persons of interest in a point-and-click format.
When normal human vision is insufficient, Aiba's special vision modes can be used to examine the environment.
Violent confrontations play out as quick time events in which Aiba runs simulations to guide Date through the fight safely.
In Somnium, the player directly controls Aiba in a subject's dream.
Although there is a strict time limit of six real-world minutes, the perception of time is different in a dream.
Thus, instead of having to contend with a constantly ticking clock, each action the player performs will shave a different amount of time off of the 360-second total, and players are given limited opportunities to change the length of time an action will take.
By interacting with objects and solving puzzles based on dream logic, Aiba can break a subject's mental locks and uncover the truth.
Certain Somnia have multiple solutions, which will send the player dow
About PlayStation 4
The PlayStation 4 (2013) cemented Sony's dominance of the eighth console generation, with a library exceeding 30,000 titles once indie and digital-only releases are counted. Most PS4 games remain affordable for collectors, but limited physical print runs — particularly from smaller publishers and later in the console's life cycle — are starting to see steady price increases as digital storefronts eventually wind down support.
Gamevaro tracks AI: The Somnium Files - Nirvana Initiative [Collector's Edition] for PlayStation 4 with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding AI: The Somnium Files - Nirvana Initiative [Collector's Edition] to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This PS4 release dates back to 2022.

Rarity & condition
Only a handful of market sales have been tracked for AI: The Somnium Files - Nirvana Initiative [Collector's Edition], suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common PlayStation 4 titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
