Soldato
On story mode, is it like free roam once you have finished the game.
After the story ends I found a few wanted posters pop up and I found a couple of quests in San Dennis that I hadn't completed, otherwise just head to a big part of the map not included in the main story which is way down west to the Amarillo & Tumbleweed area, there are bandit camps and old mines down there to explore and you can swim across to Mexico
