Keep Your Eyes on the Prize

 is a quest in Fallout: New Vegas.

Quick walkthrough
Ghost, an NCR Ranger (sniper specialty) from the Mojave Outpost, is concerned when she notices plumes of smoke rising from the reclusive town of Nipton. To make matters worse, there have been no travellers from Nipton as of late. Ghost contracts you to investigate the disturbance.

Detailed walkthrough
When you reach the town, you will see Powder Gangers crucified along the street. At the entrance to the town hall you'll encounter a contingent of Caesar's Legion, led by Vulpes Inculta. After a brief exchange, the Legion spares your life in order for you to spread the word of their atrocities across the wasteland. After the dialogue, you may enter the Town Hall, located directly behind where the exchange with Vulpes Inculta occured. Inside you will find several enemies, along with more details about the demise of Nipton found within the Mayors office upstairs.

NOTE: Killing all members of Caesar's Legion will yield little benefit. You will lose access to the quest Cold, Cold Heart and other assasination missions. Additionally your karma status with Caesars Legion will become "infamous", and there is practically no loot of value on any of the corpses. Killing all members will also not add any additional award from Ghost upon completing her quest, nor will you gain any karma with NCR.
