A candy bar is a bar-shaped confection made of chocolate, sugar, and milk. Candy bars can be found in both Deus Ex and Deus Ex: Invisible War, both in vending machines and lying around. Each bar restores a small amount of health (2hp), but several can be carried en masse and used all at once to regain a lot of health. In Battery Park, two homeless children will exchange info about the NSF for candy bars. In Deus Ex, all candy bars read "CHOC-O-LENT DREAM. ITS CHOCOLATE! ITS PEOPLE! ITS BOTH!(tm) 85% recycled material." In Deus Ex: Invisible War, they all are "MontyBites" brand chocolate bars.
"Get a health boost from MontyBites! It's the flavor of post-Collapse hipsters. The only candy that bites back."
