- This article is about the Door-locking mechanism in Metroid Prime Hunters. For the Sealed doors of the other games, see Blast Shield.
Sealed Doors are found in Metroid Prime Hunters. They will remain locked until Samus fulfills certain conditions, like destroying certain enemies or defeating rival Bounty Hunters. They have a spinning red lock on them. A few Sealed Blast Shields cannot be opened at all (only passed through from the other side) and enforce a "one way" policy. They are variations of Blast Shields and Metal Doors found in other games.
"Analysis indicates the Door is remotely locked. Something nearby may unlock it."
