 * Three can be found in the L'Enfant District, each carrying one of the three weapons that Overlords are commonly seen using (Tri-Beam Laser Rifle, Super Sledge and Gatling Laser). Careful as there are ALOT of Super Mutants in this area along with destructable cars AND Enclave Troops will land at a intersection you may pass, so things can get pretty hectic. Stealth is advised.
