How do you get legendary characters in red dead redemption

You must first get to the highest level in online mode and in the multiplayer menu you will find legend mode. click this and you will go back to level one but with legend level 1 and you unlock a legendary character, i don't know who it is. You can do this five times and on the fifth time of entering legend mode, you unlock john marston. This takes about 14 days of play. I've seen one person playing as John Marston before
