You do what the social club challenge says...
Some parts of it will not complete so basically, no.
Do your missions.
Complete gang hideouts.
There are no cheats for the social club, the social club is a mix of challenges and stat comparing.
If you want to be able to do this you need to complete the story missions on Red Dead Redemption and eventually you will unlock the higher levels of dead eye which allow you to use the X's.
There is no such thing as Red Dead Redemption black there is only the regular Red Dead Redemption and Red Dead Redemption limited edition.
you must complete the master hunter challenge of killing two cougars with your knife...tip: shoot the cougars twice in the legs and they will stop attacking you and run away..chase em down and knife em and the buffalo rifle will be available at the gunsmith
Complete the mission previous to that mission.
The multiplayer mode of Red Dead Redemption is not saved manually - it autosaves after each game you complete. I believe it also saves if you quit via the start menu.
There are two, Red Dead Revolver, and Red Dead Redemption and Red Dead Redemption Undead Nightmare
You must first complete The Wronged Women stranger quest.
there are no codes, you must complete the gun challenges
