We spend so much of our lives working. When I die, if there's some sort of afterlife, I want to just chill out. Make it look like a never-ending Corona commercial or something. Doesn't that sound nice?
That's not a position that Middle-earth: Shadow of Mordor's Talion is in, however. After the Ranger of the Black Gate was killed by Sauron's forces, he was resurrected, and the Gravewalker has a thirst for vengeance -- a thirst that can only be quenched by sticking swords and arrows in men and orcs, alike.
