Weapons
Overlords carry Gatling Lasers, Missile Launchers, Tri-Beam Laser Rifles, Sledgehammers and Super Sledges as standard weapons. In a rare case, you may find a Overlord with a Minigun. This has occurred after fast traveling to the National Archives.

If the overlord gets a hold of a two-handed weapon, such as the Chinese Assault Rifle, he will fire it one-handed.

Locations

 * West of Rivet City and East of the Jefferson Memorial
 * 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.
