Hi guys new to the board. Going to be posting some spoilers below. I've actually joined to find out a few things.
SPOILERS
So I've just finished the main part of the story with Arthur. Now I was aware that he died through reading message boards but wow what an emotional ending. The bit where my horse died was devastating and i was hoping if i ran back i could use a revive kit in the hope i could find it and use it as Johns horse. Arthur is definitely my favourite character in a video game probably since Tommy Vercetti. Anyways my point was there are tonnes of side missions I haven't done. How do I go back and do this or are you able to do all the side missions as John (I assume not).
This is a very nooby type question and I apologise.
