Survival horror games emphasize puzzle-solving and evasion over combat due to limited weapons and ammunition. Players must face threats like zombies but typically cannot directly fight large numbers of enemies. Some key aspects include exploring a mysterious setting while vulnerable, navigating different dimensions, and newer games focusing more on psychological fear through manipulating the player's mental state with limited HUD and gameplay that avoids reliance on weapons. Popular franchises in the genre include Resident Evil, Silent Hill, and Amnesia: The Dark Descent.
