Guard the brahmin

Guard the brahmin is a side quest in Fallout 2.

Detailed walkthrough
Standing outside of the Buckner House in Klamath, a simple-minded fellow named Torr tells you that "bugmen" have been raiding his brahmin at night. Agree to his plea and you'll be sent to the Grazing grounds, where Torr keeps his livestock. If his request is declined, he will not bring it up again.

Kill the radscorpions to finish the quest. You will have to go hunting for them, as they will not come when you are there. You can also confront the Dunton brothers who are standing to the west of the shack. If you agree to rustle the brahmin, you can tell them to abort the plan which will cause them to run away (requires a Speech skill of 50). You will get the same reward either way. You can also insult them, which turns them hostile, and kill them for karma reward. This will not affect town reputation.
