Claws Out

Claws Out is an unmarked quest in Fallout: New Vegas.

Detailed walkthrough
Head to the quarry and kill both the alpha male and the deathclaw mother. The mother is with the youngsters at all times. It is possible for the player to hide on top of the conveyor belts and shoot the deathclaws without them being able to get to the player, if done correctly. After the targeted deathclaws are dead, you can return and get your reward.
