Light barrier

A Light barrier (also called a Security System and a Door System) is a hatch that appears in the Metroid Prime 2: Echoes Bonus Disc. It is a white-colored force field with an elaborate design on it consisting of black circle outlines surrounding whole circles, each connected by lines. A larger circular black border surrounds a crimson circle that frequently streams a light colored beam upward. It is vulnerable to the Dark Beam; once hit, it fades away. There is another one that is completely invulnerable and black in color at the end of the Command Center Access.
In the final game, they are absent. This is because Samus does not have the Dark Beam at that time of her exploration. The Space Pirate defense shield seen in the final game bears a similar pattern of circles and connected lines as a Light Barrier if one looks closely enough. The defense shield also plays a similar role as a Light Barrier in blocking key areas.
==Scans==
"Security Systems active. Dark Beam weapon system required for door access. Energize door with this weapon to open it."
"Door System access denied. Unable to bypass security codes. Seek an alternate exit."
==Trivia==
*The indestructible Light Barrier shares its scan with that of the Blast Shields within the same game. This scan is also used in the final game for the Blast Shields seen there, with the only difference in text being the Capital S in system now lowercase.
