Once you got 2 skulls, place them in the graveyard and get the barn key which will spawn soon after. Be careful of the mini boss that will spawn in too

Once you got the barn key and killed the boss, go over to the barn and open the panel. This will open to a 3 digit number code lock. The numbers will spawn in the map, always in these locations.

1st location: In the Saloon bottom floor in a barrier window

2nd location: On top of a staircase in the hotel

3rd location: In spawn under a well roof

Input these number (in their corresponding colour place) and voila! The door should open revealing pack a punch!

Hope this guide was helpful for everyone

(Update 1: I must apologise, I thought I found all the locations after going through countless games. This has now been updated so a sixth skull location is here now. Please let me know if there maybe more)
