Replay story missions with upgrades.
Take Reed's stallion back to indian camp where you race tom. Take the horse up to far left side of the rocks you climb down with Ned when you first get there hold the L2 button to gallop up the the side and repeatedly tap the jump button and slightly twist to each side and you can climb up to the top of the rock and jump to the ledge. Go back through the pathways till you get to the very beggining, go to the water and stand between the two rocks close to the edge of the water. Press L2+L1+R2+R1+X and pause the game while the sound that plays is going(try to hold the buttons down till you pause it I don't know if it works the other way) then go to options and there will be a selection titled "Gun". Go there and you can view all the videos or choose from any side or main mission to replay and you have all your weapons including the Nock Gun for most missions. You won't be able to use reed's stallion or the cannon nock gun but it's still pretty fun. I've done it alot so I know it works.
