Many games will use a narrative event to break pre-establishing rules in order to accentuate the moment. However, the way in which this is done can dramatically affect the relationship between the player holding the controller and the character going through the narrative event. This is particularly noticeable in RPG boss fights when the protagonist is so determined to win that they become invincible through sheer determination, which ruins the player’s sense of urgency. Azure Striker Gunvolt circumvents this problem by giving the player a generous super-mode called Anthem, but also presenting new challenges which specifically target the nature of Anthem’s abilities.
