Defoe

Defoe is a black market arms dealer in the subway station under Denfert-Rochereau square. He lives in an apartment near Champs-Élysées, in building 11, as stated by several civilians who think he's out of town.

The first time JC Denton meets him, he is selling 3 rockets for cr5250 (5250 credits), 3 LAMs for cr6750, and a recoil weapon mod for cr1200. If JC asks why his prices are so extreme, he will offer him a 66% discount for killing 3 MJ12 Troopers who currently guard the subway (although there are only 2 troopers, killing them will still get JC the discount). A security bot patrols the subway, but JC does not need to neutralize it to get the discount.
