Diegetic HUD-less Interface
Diegetic interfaces delete the overlay and place health, ammunition and inventory on objects inside the fiction, so information lives in the world rather than on a layer floating above it.
Instead of bars in a corner, a spine-mounted display carries health, a projected hologram in front of the character shows inventory or the map, and ammunition counts glow on the weapon itself. Everything stays present while the character moves, and menus do not pause the world, so reading the interface costs attention and time. Camera work and lighting must then keep those readouts legible from behind at any distance.
EA Redwood Shores built Dead Space in 2008 with immersion as an explicit constraint, aiming at a horror game with no break between looking and playing. Removing the pause menu also removed the safe place where a frightened player calms down. Practicality helped: a third-person camera locked behind the character's back offers a stable surface to display data on, which a first-person view does not.
Fiction and interface stopped competing, and a run of quieter games followed by deleting the overlay rather than replacing it. Costs are legibility and access. Diegetic readouts are harder to see, cannot be resized, and tend to assume good vision and a large screen, so most games using them now ship a conventional layer as an option. Whether a stripped display deepens immersion or merely hides information remains contested.
