DEAD MAN'S HAND TIPS & TRICKS
Hidden Runestone 1
Begin the level where you have to go to the log mill to kill the "Twins". Enter one of the rooms in the three gin distilleries at the start of the level that has a "table" constructed from a wood plank laying across barrels. Use dynamite to blows up one of the walls in that room to find a hidden area. Inside is a glowing purple Runestone.
Hidden Runestone 2
In the Dead Man Walking level, when you enter the church two men will corner you. Dispose of them 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 outside the church behind the fence is a huge purple rock with the same markings as the Rune Stones.
Hidden Runestone 3
In the White Lightnin' level, make you way 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.
Hidden Runestone 4
In the Shootout At The Lazy 8 level, enter the house from the side door. Blast a few 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.
