SOMNUS is a first-person shooter built around the Perfect Evasion mechanic.

Players take on the role of Jung, an underground doctor who dives into patients’ subconscious minds using the forbidden medical technology DIVE, uncovering truths hidden within surreal dreams.

Gameplay alternates between investigation and combat.

During investigation, players gather clues and piece together fragmented memories.

During combat, precise timing triggers bullet time and restores Nightmare Fuel, letting players outmaneuver enemies that embody psychological trauma.
