Sequence Breaking
Sequence Breaking is the act of obtaining items in the game out of order, or of skipping said items entirely.
Much like Sequence Breaking in Super Metroid, Sequence Breaking in Metroid Prime has been refined into an art. The goal of the Sequence Breakers is to push the game as far as they can, either by getting the lowest percent of item pickups, by beating the game as quickly as possible, or by beating the game as quickly as possible with all items (100% pickups).
