I feel like Red Dead Redemption is creepy enough without zombies. When you're playing the original bare-bones Red Dead Redemption, it always feels like something is amiss. Everything seems too quiet, like John/Jack Marston is stuck in some sort of purgatory. When something does happen(such as bandits riding through town firing pistols into the air) it always seems distant, sort of muffled. Whatever cacophonous reports happen to sound die away almost instantaneously. The music only adds to this, especially in Blackwater and Tall Trees. Hmm.
