Grayson

Grayson is a character in Deus Ex: Human Revolution. He's an arms dealer in Detroit.

Background
He operates from the abandoned gas station, just across the LIMB clinic. He sells various types of weapons, ammunition, weapon upgrades, explosives and miscellaneous items.

As with any other merchant in the game, players may also sell their items to him.

Upon Jensen's return to Detroit from the Picus building, Grayson's inventory will be restocked with better items.
