Lucas Simms

Lucas Simms is the sheriff and occasional mayor of Megaton, a town built around an unexploded nuclear bomb. He would like the bomb disarmed, despite the fact that it is worshiped by a local cult known as Children of the Atom. If you disarm the bomb, Simms will give you the keys to the Megaton Shack in Megaton. If Lucas Simms is dead his son Harden Simms will give you your reward.

If you inform Simms of Burke's plan to destroy Megaton, he will attempt to arrest Burke. This prompts Burke to try to kill Simms.Which depending on how you react during this confrontation can end up in his or Burke's death

He carries the key of Megaton Armory.

Known Bugs
Lucas Simms is one of the named Megaton residents who may mysteriously die and leave no body.
 * I had a variation of that bug: When confronting Burke, I managed to kill him (Burke) before he managed to shoot Simms. This caused Simms to disappear. I later found his dead corpse near the entrance for no particular reason.
 * Another issue: if you enter VATS as Lucas turns and Burke pulls his gun, and kill Burke before he shoots, Simms can still die. Simms' death appears to either be scripted to the end of the conversation, or Burke (almost always?) scores a Sneak Attack Critical on Simms.


 * I had no issue killing Burke after the confrontation with Simms. As soon as the conversation finished,and Burke drew his gun, I entered VATS and a few headshots later with the 10mm it was ended.  Ran into Simms a little while later and he thanks you (no reward afaik)


 * Best time to enter VATS is to follow Burke as he gets up from the chair after his talk with Simms and enter VATS immediately after the gun (10mm silenced pistol) manifests on his right hip. This way you can get off your shots even before he draws his gun, thus maximizing your chance of saving Simms.
