D.A.V.I.S. is a single-player Unreal Tournament 3 total conversion mod that takes place in an abandoned 1950's American suburban utopia. This cerebral suspense game utilizes environmental puzzles, sophisticated sound design, and rich visual environments to create a creepy, eerie, and tense atmosphere that keeps the player alert at all times.

D.A.V.I.S. plays out in three acts, each one leading the player though the psychology of Katherine, a woman who has been living completely alone in the abandoned suburban town for a few years. Katherine’s grasp on reality and fiction has waned in her isolation, making her fragile and unpredictable. When the player, Alex, arrives in D.A.V.I.S., Katherine uses him in an intricate game to try and validate the world that she has constructed for herself in and around the buildings of the abandoned town. Alex and Katherine's “relationship” eventually implodes when Alex discovers the secrets of D.A.V.I.S. and Katherine herself, causing her to have a psychotic break that marks him for permanent removal from her world.

It’s up to the player to guide Alex through D.A.V.I.S., solving puzzles to unravel the mystery surrounding Katherine and the town in order to find a safe route back to civilization.
