You are the Avatar, the hero of heroes, and once again you must save Brittania. This Ultima Underworld pack includes Ultima Underworld: The Stygian Abyss and Ultima Underworld II: Labyrinth of Worlds, both by Origin Systems. Save the princess and escape from the Stygian Abyss and then save everyone in the Labyrinth of Worlds. Each of these games gives you an epic challenge and an immersive adventure to embark upon. Play the first true 3D dungeon crawler that defined the genre and was so innovative that some of its features didn’t show up regularly in other titles for a decade or longer. Experience the freedom of an Underworld filled with hidden areas to explore and dozens of NPCs to interact with.
