I thought I’d throw together some of the more common questions as a starting point.
Excuse the formatting, I’m new here and missing the Apollo features to do it properly.
Will my horse respawn?
All the wild horses respawn. You can only have one of any given horse at a time, but if it dies or you sell it, it will respawn at the original location in around 3 in-game days.
This applies to
White Arabian;
Red Chestnut Arabian;
Warped Brindle Arabian;
Perlino Andalusian;
Tiger Stripe Mustang
Several unique horses exist that do not respawn. These are:
Mahogany Bay Tennessee Walker found at Adler Ranch in Chapter 1;
Black Shire from Chapter 2;
Buell from the Veteran;
Rachel from the epilogue
What transfers to the Epilogue?
You keep the unique items (Eg dinosaur skull), weapons and clothes but you lose all perishable items and most valuables.
These items don’t carry over:
Horses;
Gold bars;
Gold nuggets;
Cash;
Jewelry, watches, belt buckles etc;
Herbs;
Food
So how do I get money fast in the epilogue?
There are a couple of options:
Buy everything you can before the epilogue. All the weapons, all the clothes. If you’ve done the treasure hunts, you can actually afford every single item of clothing (in every colour), all the guns etc. Do this and you won’t need much cash in the epilogue. This is my go-to method, it’s also useful if you’ve missed your chance at the next method.
Use the Aberdeen Pig Farm method. Turn all your assets into cash, then pay a visit to the farm before the epilogue. Let them rob you, but don’t go back for your money until you are in the epilogue.
Quite a few gold bars and nuggets respawn in the epilogue, giving you plenty of ready cash.
Gold bar at Limpany - this actually spawns multiple times through the game. ;
Gold bar at Braithwaite Manor;
Gold bars at the train wreck ;
Gold nugget at the wagon in the burnt out forest area west of Horseshoe Overlook ;
Gold nugget in the abandoned wagon just north of Owinjila ;
Gold nugget at the abandoned wagon between Valentine and Emerald Ranch
I’m using Voyager, as the community name suggests the OP is. Using the AppStore version on iOS which may make a difference.
