ABOUT THIS GAME:

From the creative minds behind the acclaimed Ultima Underworld®, System Shock and Thief series. In Underworld Ascendant®, Paul Neurath and Warren Spector's OtherSide Entertainment challenges you to think creatively in an interactive sandbox environment.

You are summoned by a mysterious figure to The Stygian Abyss, a dangerous and constantly evolving dungeon world imperiled by the looming threat of the beast Typhon.

To save this world, and yours – you must overcome complex challenges, uncover lost secrets and gain favor with factions to maximize your knowledge and strength. Utilize your environment to stack the odds in your favor. Devise the ideal plan to overcome the challenges you face or dive in and think on your feet.

Each decision holds great opportunity and grave consequence. What you leave behind will be engraved on the lives of others. Assuming you survive…

A DEEPLY IMMERSIVE WORLD

Enter a fully-realized dungeon realm, from the village of Marcaul to the Vault of Nyx and seven other large-scale levels to explore, each comprising a labyrinthine assembly of rooms, passages, halls and ruins connecting massive cavern complexes.

Encounter fantastic creatures like Lizard Men, opportunistic Outcasts, and fearsome Mind Cripplers – all with unique abilities that can be used to your advantage.
