The visuals in Post Mortem take on a primarily first person panoramic style view. Backgrounds are portrayed in richly detailed settings, though the images are purely static and immobile. Characters take on an appearance similar to the odd, sore portrayals of human beings in the Resident Evil series. This creates an odd eeriness whenever talking to suspects or informants, though the distraction is not unpleasant. However, the repetitiveness of the character animations during conversation brings out the flaws in Post Mortem's visuals, exposing dull uninteresting character art and backgrounds.
The dialog in an Adventure title generally carries the player throughout the game. In Post Mortem, some dialog is simply hit or miss. In general, characters speak too slowly for the game to progress. There are no ways to skip dialog either, so expect long, drawn out conversations that often lead absolutely nowhere.
