See also levelIn an open world game such as an RPG, dungeon refers to any enclosed areas filled with hostile NPCs where the player is likely to come under attack. In this sense, it can be used to refer to literal ‘dungeons’ or include any number of other places, such as caves, ships, forests, sewers or buildings. Dungeons may be maze-like and/or contain puzzles that the player must solve and often hide valuable items within to encourage player exploration.
