Eye for an Eye (Fallout: New Vegas)

 is a quest in Fallout: New Vegas.

Quick walkthrough
After discovering Cottonwood Cove, First Sergeant Astor asks the player to collect some intel on Legion troop movements and raids from Cottonwood Cove and plant a bug in their radio. The Legion raid intel is in a cabinet near the buggable radio on the first floor HQ Building; the intel on Legion troop movements is in the desk on the second floor. Returning to Astor with the intel provides 500 XP & the player gets the option to wipe out all Legion forces from Cottonwood Cove. This provides NCR fame, Legion infamy (if they spot you in the act) & 1000 XP. Also, when playing as a female character, and you wiped out the legion forces in combat, Sergeant Astor will comment on this, and you will receive 1100XP instead. Alternatively, you may also accept bad intel from Aurelius of Phoenix in conversation & disseminate it to Astor for Legion fame & 500 XP.

Detailed walkthrough

 * When you recieve the option to wipe out the Legion fort, Astor calls you crazy but believes you can pull it off. To get the most fame with the NCR, locate the red truck hanging precariously off the cliff over the Legion camp. Your geiger meter will show radiation leaking from the truck when you get close. Go to the back of the truck, and select the door. The option to open the door becomes available (50 lockpick required), dropping several radioactive barrels into the camp, effectively killing the Legion the same way they killed the NCR forces at Camp Searchlight. Astor is quite pleased with this outcome.

If you do this before freeing the slaves, you'll lose the quest "Left My Heart". The Weathers can be found in a locked pen behind the Storage Building. They are wearing slave collars that need to either be safely removed, maliciously detonated or provided the key in which case they'll unlock themselves and escape.

Note: If you had already cleared out Cottonwood Cove before talking to Astor, you can simply break the news in a conversation with him. You will recieve NCR fame and 200 caps.

Bugs
Sometimes dropping the radioactive barrels will not kill all the legionaries. They will remain standing in front of the barrels without ever succumbing to the radiation.

Astor doesn't always give this quest, if you walk through camp searchlight and then into Cottonwood - anytime you fast travel back to Camp Searchlight the NCR NPC's are mid-way through a fight with legion troops and Astor is nowhere to be found.
