-On the level where the boss is playing an old phonograph, find the three hidden watermelons in the following locations: just before going down to the wall of adobe buildings on the left; hidden in a deep gully; and on top of the mountains. Shoot all three of them to play a shooting gallery mini-game.
-When you start of the Lead And Whisky level (bonus mission), go into table of melons in the middle of four buildings. Turn and face the way that you came from. High atop a mountain you will see Secret Melon 1. Continue down until you reach a ledge between two buildings. Secret Melon 2 is at the bottom. If you are standing in the correct location, the last melon is to your right, between two boulders. This starts the mini shooting game.
-Start the level where you have to go to the log mill to kill the "Twins", then enter one of the rooms in the three gin distilleries that has a "table" constructed from a wood plank laying across barrels. Use dynamite to blow up one of the walls in that room and reveal a hidden area. Inside is a glowing purple Rune Stone.
-In the Dead Man Walking level, two men will corner you when you enter the church. Take them out and go to the back right corner inside. Take off the crooked door with a shotgun blast. Enter and blast the left wall twice with the shotgun to reveal a hidden room containing a purple Rune Stone. Also, note that behind the fence outside the church is a large purple rock with the same markings as the Rune Stones.
-In the White Lightnin' level, proceed through the shacks until you reach a house. There will be TNT on the right side of the house. Inside will be a table fashioned out of a door and two barrels. Toss a lit TNT stick into the back wall of the house to reveal a hidden room with another purple Rune Stone.
-During the Shootout At The Lazy 8 level, enter the house from the side door. Blast a couple shots with the shotgun at the middle of the wall as you walk in to reveal a hidden room with yet another purple Rune Stone.
