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.
- 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.
