Hello everyone, I am here to show/explain a new thing that I just found. It I how to get a 10 cent perk in the new zombies map buried.
Step 1... First you have to get the ballistic knives out of the box.
Step 2... Then you make your way to the saloon and shoot a knife into the bulls eye. The piano will start playing.
Step 3... Then you make your way to and through the haunted house/ mansion.
Step 4... Re enter the house, turn left and then tip the witch playing the piano.
Enjoy the free perk.
