Machine Head

Machine Head is a challenge perk in Fallout: New Vegas. It is given for completing the "Demise of the Machines" challenge.

Effects
You gain a bonus damage to robots (Mister Gutsy, robobrain, protectron etc...)
 * Rank 1: +3% damage
 * Rank 2: +6% damage
 * Rank 3: +10% damage

Requirements
The player must kill 50 robots for one rank every time.

Bugs

 * Although there are 3 ranks for this perk, a bug in the reward script makes it impossible to get the third rank. The same bug also causes the notification to misreport the rank that is given. When rank 1 is given, the notification says that you've been given rank 2, and when rank 2 is given, the notification says that you've been given rank 3.
