All-Range Mode

All-Range Mode, also spelled All-Range mode, is a mechanic used by Arwings in several Star Fox games. It was first designed in Star Fox 2, but made its first actual appearance in Star Fox 64. An Arwing's pilot can arbitrarily activate All-Range Mode, and in doing so, they can freely move their Arwing around in a wide, open area rather than be forced to travel down a fixed path. All-Range Mode is often used during boss fights. If an Arwing reaches the boundaries of an area, it automatically performs a U-turn back into the arena.
