level up. do that by killing players, complete gang hideouts and complete little missions in your journal
you unlock different multiplayer modes such as hardcore etc and you unlock different characters and mounts eg. horses, bulls, ox's etc :)
go on multiplayer and press triangle/y then go through steps u keep golden guns but loose mounts and guns but unlock mounts early
yes, you get extra characters and mounts
no you can't im afraid. you can ride buffaloes though in multiplayer
You start all the way back to level 1, But you get to unlock mounts earlier, and new legendary mounts.
You unlock them as you level up through the red dead redemption multiplayer
you must reach a certain level in online mode
You unlock the super bull the fourth time you reach level 50 with multiplayer xp
You unlock the mount Zebra at the highest level in multiplayer, which is 4th Legendary level 50.
Okay well, in multiplayer you will eventually unlock it, but the only thing is I don't really know about in singleplayer/campaign
there is only online multiplayer in red dead redemption
no
