Monst3r's portrait

I've got something you might be interested in. I need a quick decision — this thing's hot.
—Monst3r

After the first mission, Central re-establishes contact with Monst3r, a freelance trader of items, weapons and augments whom Invisible has had prior dealings with.

On the world map screen between missions, the agency sometimes has the option to purchase something from Monst3r, for a 20% discount compared to their nominal value. Whether or not he has anything to sell, the agency also has the option to sell items, weapons or uninstalled augments to Monst3r, for half of their nominal value.
