I just started playing Fallout 3 again.A while back,I managed to disarm the bomb in the center of Megaton.Naturally,I wasn't expecting Burkes to shoot Simms after I reported it.I mourned his death...

But,after just starting the game,I entered Megaton and started walking down the big hill.Wouldn't you know,here's Lucas standing there,well and alive!

I'm pretty sure I remember Burkes killing him,as I definitely remember his boy talking to me after his death.Glitch/bug,anyone?Or am I just too simple minded to remember me being able to kill
Burkes on the second he pulled out a gun?:P

....Ooorrrr,are zombies SUPPOSED to rise in Fallout? XD

Sounds like a glitch to me. Though it's never happened to me. :shrug:
