AI: The Somnium Files

You play a detective investigating a bizarre murder, switching between walking around crime scenes clicking on clues and diving inside a suspect's dream to search their subconscious for hidden objects. Conversations are full of jokes and odd characters, but the mystery underneath gets genuinely dark. It rewards paying close attention, since small details from early scenes matter later.

Screenshots & review notes

AI: The Somnium Files screenshot 1: The short version

The short version

It juggles tasteless jokes and genuine heartbreak better than it has any right to, landing on a finale that reframes everything that came before. A must for mystery fans burned out on convention.

In the hands

Somnium sequences turn dream logic into actual puzzle mechanics, forcing odd, playful solutions under a ticking clock. The traditional investigation segments are comparatively straightforward but still satisfying.

Look and sound

Character designs are memorable and the voice work carries a ton of personality, even if some environments look a touch flat on the small screen. Loads without much fuss on Switch.

The long haul

One playthrough covers the core mystery, but branching paths and hidden dialogue give completionists plenty to chase. A great pick for anyone who enjoyed the Zero Escape series.

What it's like to play

You play a detective investigating a bizarre murder case, alternating between straightforward investigation sections where you examine crime scenes and question suspects, and surreal dream-diving sections called Somnium, where you enter a suspect's subconscious and solve strange, symbolic puzzles against a six-minute time limit. Solutions inside a Somnium rarely follow normal logic, instead asking you to think about what an object or action might represent emotionally to that character, which takes some adjustment if you are used to more literal puzzle design. Like the same team's earlier work, a flowchart lets you revisit past decision points to see how different choices change the story.

Your goal is to work out who is behind a string of bizarre killings, and different story routes reveal different pieces of that larger truth, so seeing the full picture means exploring more than one path through the flowchart. The tone bounces between crude jokes, real emotional moments, and a mystery that gets stranger the further you dig, anchored by a chatty AI companion who rides along in your eye. A full playthrough covering the major routes takes around twenty five hours.

Some of the humor is juvenile and sits oddly next to the story's darker turns, which will not land for every player. Somnium puzzle solutions can occasionally feel like guesswork rather than clear logic, especially the first time you encounter a new kind of interaction. It suits players who enjoy strange, ambitious detective stories and do not mind a mix of tones that occasionally clashes.
