Machine Head

Machine Head is a challenge perk .
==Challenge requirements==
This perk is rewarded upon completing each rank of the Demise of the Machines kill challenge:
* Rank 1: Kill 50 robots
* Rank 2: Kill 100 robots
* Rank 3: Kill 150 robots
==Effects==
Gaining this perk grants an increase to damage dealt against robots, increased with each rank completed:
# +3% damage against robots
# +6% damage against robots
# +10% damage against robots
==Affected robots==
==Notes==
* The perk pairs well with other damage perks such as Lord Death and Robotics Expert as their benefits stack.
* The robots at New Vegas Steel and in the Y-17 medical facility re-spawn every 3-4 game days.
* As long as one does not complete Wild Card: Change in Management, Yes Man's ability to respawn in a "new" Securitron chassis after being killed can be exploited to fulfill the challenge.
==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.
