You'll Blind Somebody

You'll Blind Somebody is a perk that can be unlocked and obtained by the Courier in Fallout: New Vegas.

Characteristics
This challenge must be earned, just as with the Bug Stomper or Animal Control challenges. To complete this challenge, the Courier must achieve 4,096+ damage by way of headshots with rifle-gripped energy weapons.

Reward
Awards 100 XP upon completion.

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.
