Take a look at the newest Cineastic Euphoria Ragdoll Rework (CERR) mod that tweaks the physics engine settings to make deaths in Red Dead Redemption 2 more realistic. Now each zone on the NPC's body has its own set of reactions. Characters stay on their feet after taking damage, hold on to the wound, or try to resist the pain. Every gunfight looks way more cinematic now. Euphoria physics fans will appreciate this mod. In addition, CERR effects the immersion, because the painful consequences of each shot will make the player think and affect the karma of the protagonist. You can download the mod here.
