Samus targets the nodes of a Multi-lock Blast Shield in Metroid Prime 2: Echoes.

A Multi-Lock Blast Shield is a shield that has five nodes that must be destroyed at the exact same time, in order to disconnect/destroy the shield. They appear as purple Blast Shields in Metroid Prime 2: Echoes and of differing appearances and use in Metroid Prime 3: Corruption and Metroid: Other M.

Seeker Missiles are required to open a door with this Blast Shield. They have been used by many races, to secure areas of importance. Some have been developed as shields for doors, while others are created for holding locks in place and so on. Their appearance varies greatly between the planets and stations they are used on. Despite the aesthetic differences, the method of dismantling them remains the same.

Metroid: Other M features the Multi-Lock Blast Shields in a considerably lesser role. There are only three within the game; one blocking the path to Sector Zero and two near Room MW in the Bioweapon Research Center.

Logbook entryEdit

Logbook entries
Metroid Prime 2: Echoes "There is a Blast Shield on the door blocking access. Analysis indicates that the Blast Shield is powered by 5 energy pods nearby. Destroy all 5 pods at once to remove the Blast Shield."
Metroid Prime 3: Corruption "This type of Blast Shield is characterized by its multiple locking mechanisms. A simultaneous blast to all the targets is required to deactivate the locks and remove the shield."


  • Most Multi-Lock Blast Shields in Corruption are obstacles rather than actual shields covering doors. Only one covering a door is ever found in the game, in Cargo Dock B. This door is colored yellow in the key of the game.
