Body Armor
From Goldeneye: Source
Body Armor is a protective vest worn by the player to increase longevity. There are several body armors strewn across each level, of which all respawn relatively fast. Worn body armor is displayed as a blue health bar on the opposing side of the screen.
[edit]
Use
Body Armor is a very vital element to most forms of gameplay in Goldeneye. It can easily be the determining factor between a 20-30 kill/death ratio and a 50-10 kill/death ratio. Not only does it have the potential of giving you the equivalent of 200% health, you can also keep picking it up as your armor goes down. Because of this, players can go extended periods of time without dying. You cannot pick up armor if you have picked up the Golden Gun.
