After shooting the 8 perk bottles, we all got Perkaholic! Very nice!
Here are the locations of the bottles:
1 next to the turret (on dryer behind power),
1 on wall corner above hell's retriever,
1 on the the bank hut chimney,
1 in the left corner of staminup,
1 under pap,
1 next to mule kick at top,
1 on the floor of the elevator lift, right back corner.
1 on the corner of the bed (near the door, behind the boxes) in the bank hut.
(They break and need to give off a purple smoke when shot).
