You'll Blind Somebody

You'll Blind Somebody is a challenge in Fallout: New Vegas.

Characteristics
This challenge is completed by inflicting 4,096 headshot damage while using rifle grip energy weapons.

Rewards

 * 100 XP

Bugs

 * The challenge gets stuck upon reaching the 4096/4096 goal and after that every single energy weapon headshot for the rest of the game triggers the XP award and displays the achievement message without actually marking the challenge as complete.
 * Similarly to the PC bug, this challenge may never complete. Instead, upon reaching 4096/4096 it will simply reset to a lower value. Unlike the PC bug, however, it does not seem to be possible to get infinite experience (or any at all) from this challenge.
