Some more brand new screenshots from the Red Dead Redemption Undead Nightmare pack have been released and can be seen below:

An especially vile and luminescent zombie looking for sustenance.

A horde storming through Blackwater.

Townsfolk come face to face with the undead menace.

A rather heavy set zombie lurking in the shadows.

Preparing for a confrontation on the countryside.

While usually considered a
cowardly and dishonorable act, Marston has no qualms about shooting
these mindless adversaries in the back.
