Marston examines a missing persons bulletin, one of the new Challenges in Red Dead Redemption: Undead Nightmare.

In the wake of the horrific zombie plague that is reawakening the dead in tomorrow's Red Dead Redemption: Undead Nightmare, several citizens have gone missing across the world.  During his journey across the frontier to find a cure, John Marston will often come across posters calling attention to those that have mysteriously disappeared.

To begin the search for a Missing Person, look for these posters in clean zones throughout your travels.  Clean zones are areas under tight military control and are relatively safe from the undead menace.

Approach with caution.  Arriving upon a missing person's last known location...

Marston gets some help cleaning up around the house.

The road less traveled is often the safest.
