Light describes and defines the general build and size of a created character in Brink, and is assigned through the Character Customization menu. A light character will only be able to wield light weapons and will also start with the lowest base health, but will be more agile than a character of a medium or heavy build. This means that light characters will be able to run faster, jump higher, and be able to execute more parkour moves than any other build. The light body type will not become available until level 7. the best build in all of brink and I know a Glitch to get heavy and medium weapons as a primary=)
