While there are many horror games that pit players against undefeatable enemies, this is usually due to players being deprived of the ability to fight back. This can be tremendously frustrating for certain players, and can even pull players out of the experience as a result. Survival-horror games have to handle undefeatable foes in a different way, however, as weaponry is often a key factor in survival-horror gameplay. Either way, horror games that include undefeatable foes must tread a fine line in order to provide players with an intense experience.
