AI: THE SOMNIUM FILES - nirvanA Initiative

Special Agents Ryuki and Mizuki, each paired with an AI partner, investigate the Half Body killings: a case involving body halves discovered six years apart. Their work uncovers connections between the murders and a wider mystery.

Players explore locations, inspect evidence, question people connected to the case, and reconstruct events in virtual crime-scene sequences. They can also enter suspects’ dreams to search for clues through puzzles shaped by each dream’s rules.

The investigation shifts between the two agents and events spanning six years. Dream sequences use logic-focused puzzles, while choices and story routes let players revisit scenes and pursue different outcomes.

Players who enjoy the game often praise its more logical dream puzzles, its layered mystery and twists, and the humor and interactions among the cast. Some also highlight the voice acting and presentation. Critical reviews frequently find the story’s structure confusing or overcomplicated, and describe stretches of investigation as slow or repetitive; opinions on the central reveals and character writing vary considerably.
