Red Dead Redemption

Give the nuns money whenever possible. Attaining maximum honor and fame may help. 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.

Get your Honor to its lowest point. When you whistle for your horse, a message stating that your Deeds have led to a dark horse becoming your stead will appear. If you do any good, it will go away.

Wait until a girl tries to steal your horse, or during the random encounter where there are bandits behind a stage wagon. Kill the bandits and hogtie the girl. Find a train on your map and put her on the tracks in front of it.

Note: The entire process takes place while the player is under the palace with the following glitch. Travel to Escalera. There is a palace at the top surrounded by cement walls. Enter through the doors. Note: Only one set of the doors work. Enter the palace and turn left. You will see a potted plant in a corner next to a bookcase. Get behind the plant by either jumping over it or walking behind it. Face the bookshelf and crouch. You should fall through the floor; if not, spin in circles while crouched until it happens. If you end up in some random room with no doors or windows, you will be stuck and must kill yourself to be freed. Once under the palace, you can shoot through the walls but no one can shoot back. To leave the glitch, simply walk out of any of the "walls." Attain a bounty of $1,000. Maintain the public enemy pursuit for ten minutes of real time. Make sure the Mexican army stays on you for that period of time. Wait for the pursuit to dissipate. Let the pursuit die out to unlock the achievement.

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.

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

Press Left Analog-stick Left, Left Analog-stick Right repeatedly instead of following the in-game instructions. Although the horse will buck around, it will eventually end up broken.

When you're breaking a horse, be it for a mission or your own personal amusement, to avoid getting thrown off the horse simply move the left analogue stick left and right repeatedly, ignoring what the game tells you to do. The horse will buck around a bit more than usual, but you'll end up breaking it successfully without the massive aggravation of doing it the standard way.

Find one of the bird shooting challenges. They are usually easy to find; just listen for shots and watch for a lot of birds circling in the sky. Accept the challenge and intentionally lose. The wager will then double. Repeat this until you have just enough money to make one more bet. Then, watch the sky and wait until you can see the amount of birds you need to win the bet. Accept the challenge, then go into Dead Eye mode. Take down the proper amount to win. Note: It may help to have moonshine or chewing tobacco in case you run out of Dead Eye. After you win the bet, put on your bandanna and kill the man you bet against. Loot his body and he will have the same amount of cash as the final wager. The more money you have to work with, the more you can make. It is possible to loot over $20,000 from him.

Kill an animal, then walk over it slowly. Press R1  or RB  Xbox 360  to come to a stop over the dead animal. Next, press Triangle  or Y  Xbox 360  to get off, then press the button once again to skin animal, then press it one last time to get back on your horse. This works well when you are being attacked by packs of wolves or when hunting grizzlies or cougars.
