Cthulhu Mysteries: Veins of Arkham is a narrative, investigation-driven adventure set in 1931, blending noir detective storytelling with slow-burn Lovecraftian horror.
You play as Claude, a Chicago police detective assigned to a series of unusual suicide cases—four victims, each dying under identical circumstances, each hiding pieces of a much darker truth.

As you explore crime scenes, question witnesses, analyze documents, and connect clues in your notebook, the investigation slowly reveals the presence of a secret cult operating in the shadows of Arkham. The deeper Claude digs, the more unstable his reality becomes—visuals darken, the atmosphere distorts, and the line between sanity and obsession begins to erode.

Your actions shape the final outcome:
– expose and dismantle the cult,
– succumb to the madness,
– or meet an untimely end as the truth closes in.
