Hidden Treasure 1: Rhodes’ Gold

Rhodes’ Gold is located at Hanging Rock, north of Armadillo in Cholla Springs. The chest can be found at the base of the largest boulder, under a pile of rocks in a narrow area, which can be reached by exploring the north side of Hanging Rock and following the narrow path such exploration reveals.

Hidden Treasure 2: Jackson’s Gold

Jackson’s Gold is located just east of Rio Bravo near the Rio Del Lobo, at a location called "Del Lobo Rock". Find the gap in the rocks at the top of the cliff indicated on the treasure map, and save your game (in case you fall down to the riverbed). Move through the gap, and go to the right. Then, switch back to the left, and hug the cliff face until you can drop down into the shadow of the bulbous outcropping. Look at the map for a depiction of this route. The treasure can be found on a small ledge.

Hidden Treasure 3: Calhoun’s Gold

Calhoun’s Gold is located in the basement of the old mansion in Tumbleweed. Enter it using the back cellar entrance on the west side, and walk straight until you reach the basement wall. The treasure can be found below a mounted bull skull on the wall.

The stool-shaped rock in the first two treasure map illustrations is just off the main road leading northwest from Casa Madrugada, just above the armadillo on the main map. From the stool-shaped rock, look southwest, and you should see a path that begins just above some rock spires. Follow it to its end to find the treasure.

Hidden Treasure 8: Pickett’s Gold

Pickett’s Gold is located east of the ranch at Beecher’s Hope, near a large tree split by a lightning strike. The treasure is buried in a gap in the stone fence north of the tree.

Crucifix
Achieve maximum fame and honor, and a nun will eventually approach you. She will tell you that she and the other sisters have been gathering items to help your righteous cause. She will give you a cross that makes enemies less likely to hit you with bullets. Note: You must remain honorable for this to remain in effect.

Harvest animals for health
Reach Level 10 Master Hunter to unlock the ability to harvest animals for a health item.

Easy experience
Play in online Free Roam mode. Find a gang hideout, and kill all the enemies, as well as the reinforcements that appear. Loot the bodies to get money and ammunition, then leave the hideout. After a short amount of time, the enemies will respawn, allowing you to repeat the process as many times as desired.

Easy money and honor
Accept a bounty mission. Go set up camp somewhere, and save your game. Capture or kill the bounty target, and return to the sheriff to get your money and +100 honor. Then, go run into some water and die. When you respawn in one of your houses, the bounty mission will still be active, and you will also keep the money and honor you just received for completing the mission. Repeat this as many times as desired.

Easy fame and honor
Go to Thieves' Landing, and buy the Elegant Suit. Then, go in the saloon, and play poker ($25). Get caught cheating by pulling the arrow to one side. You will then have to duel with someone. Shoot the gun out of their hand for extra fame and honor. Note: When you do this, the bullet may ricochet and hit someone else. If this happens, they will start shooting at you. To make this easier, buy the house in town to save the game and stop others from coming after you.

Easy reloading
When you are low on ammunition, enter Dead Eye mode. Your ammunition will be refilled without needing to reload.

Easy herding
When you are herding, stand far back and just ride very slowly. The herd should follow the person in front of the herd.

Easy quick save
Obtain two different horse deeds. When you want to quick save your game, simply switch horses by using the other deed, and your progress will be automatically saved.

Determining horse breeds
If you go to the general store, you can purchase horses by buying a deed for them. Instead of buying the deed, check the info, and it will give you a description of the horse's appearance. You can compare this information with horses you break to help determine the horse breed.

Another good way to determine a horse's breed and quality is to break and ride them just a few seconds. You should be able to instantly tell the difference between a 1-star, 2-star, and 3-star horse. The stamina will deplete much quicker the lower the quality, and the horse itself will not run as fast. Physically you can also tell a difference. If you can see any ribs or bones, the horse is low quality, while thicker more muscular horses are the 3-star ones. You can get the 3-star Pearl from the "Bonnie" mission very early in the game. The Hungarian Half-bred is found in Mexico and is an off-white color. The Standardbred Pinto is all black and can be found in Mexico. Other horse breeds that can be found throughout the game are American Standardbred, Ardennais, Cleaveland Bay, Dutch Warmblood, Friesian, Highland Chestnut, Kentucky Saddler, Lusitano, Painted Quarter Horse, Painted Standardbred, Quarter Horse, Tersk, Tobiano Pinto, Turkmen, War Horse, and Welsh Mountain.

There Will Be Blood reference
The town of Plainview is a reference to the main character Daniel Plainview, played by Daniel Day Lewis, in the movie There Will Be Blood. Take note of all the oil rigs.
