Hard Light Bridge



A Hard-Light Bridge (simply known as a Light Bridge,) is a semi-translucent solid made from natural sunlight beamed in from the Earth's surface. It can act as a bridge for the player, a shield against turrets and other hazards, or even a wall for more complex puzzles the player encounters later on. Light Bridges first appeared in the Flash Version MapPack and then in Portal: Still Alive, but were more formally introduced in Portal 2. The bridges span an infinite length or until stopped by another solid. Although the bridge is made of light, if one portion of the bridge is stopped by a solid object the rest will not continue as a beam of light normally would. Also, portals need to be in center with the bridge if trying to get it to another place, otherwise it won't pass through.

Hard-Light Bridges can also be covered in Mobility Gels, allowing the player to use the gels in places where it normally would just fall through. Gels placed on Hard-Light Bridges are not permanent and disappears the moment the bridge dissipates or moves to a different location. (This can only be seen in custom-made maps, as the Bridges and gels do not co-exist in the main Portal 2 game.)

Trivia

 * The Hard Light Bridge was originally referred to as "Blue Plasma Wall" in Portal: The Flash Version
 * Despite GLaDOS warning the player that the Hard Light Bridge would [[Media:GLaDOS_sp_a2_bridge_intro01.wav|set their hair on fire if they rubbed their cheek on one]], rubbing any body part on the bridge actually does not cause any harm to the player.
