Kill Darion

Simply kill Darion (near where the big computer is inside every vault, 3rd to your right) and you'll be awarded a generous amount of experience.

Bugs
You may encounter a bug, where the squatters leader will say, "Why the hell did you kill him, we are going to die.", whereas him dying should've saved him.


 * This is actually not a bug the squatters depend on the raiders for food and water, but if you kill Darion the leader might also be grateful to you. It is unestablished what exactly causes the two different reactions.
