Often, downloadable story content in single player games feels either tacked on and lazy (Mass Effect 3's Omega) or something that should have been included in the first place (Asura's Wrath's entire final chapter.) Some companies do manage to get it right; Dark Souls' Artorias of the Abyss content is among the game's best, and the Left Behind side story in The Last of Us is wonderfully made. First Light, a downloadable prequel for Sucker Punch Production's Infamous: Second Son, manages to take things even further and surpass the base game in many ways.
