Red Dead Redemption 2 is bringing several changes to the gameplay formula introduced by its predecessor. Among the changes are those to the horse mechanics, which allow players to develop a bond with their horse to improve its abilities and more. Horses can also die permanently, and it seems like this choice wasn’t just related to gameplay.

Speaking with GamesRadar, Rockstar North director of technology Phil Hooker explained that permadeath helps cement the bond between the player and the horse.
