Red Dead Redemption is a classic Western video game by Rockstar games (great game by the way and a great story if you like Westerns).
Rockstar has just released a downloadable add-on for Red Dead Redemption entitled Undead Nightmare. It's a new standalone adventure that sees the erstwhile hero, John Marston, fighting an undead plague in the old west.
Sound like a GGE storyline? It sure does. As I may have mentioned a few hundred times, we love to write, read and watch cross genre stories. Looks like we're not the only ones.
