We're weeks away from the launch of Red Dead Redemption 2, and Rockstar is ramping up with a steady stream of new details. Today the studio outlined the wide variety of fauna to be found in the Old West, which can be hunted, skinned, and sold in your spare time between missions.

The official blog shows several species, including deer, coyotes, wolves, vultures, eagles, alligators, bears, fish, gila monsters, and various horses. Hunting and fishing will provide you with food, crafting materials, and income. Your choice of weapon will impact the value of the meat or pelt, with the bow being your best bet for a clean kill. You can then skin and butcher the animal yourself or take it with you. If you leave an animal out for too long scavengers will come to take your kill before you can use it.
