Once in a while, you may encounter escaped convicts and will ask for your help in shooting their chains. Do so and they’ll give you tips about possible robbery targets like farms and homesteads.
Should you decide to rob such location alone, it will be better to sneak during the evening when the occupants are asleep and you don’t have to hurt them which can result to an honor loss or even bounty that will offset your loot’s amount.
You can also get such missions from your gang members. Doing these side tasks is much easier and rewarding with gang members than doing it alone. These particular gang-related tasks can give you a lot of money in terms of looting bodies, items, and lockboxes. You can even unlock new weapons by finding hidden guncases.
