Return to The Stygian Abyss…


This is it! The next-generation PC follow-up to Ultima Underworld, the series credited with creating the ‘immersive sim’ genre & influencing such game series as BioShock, Deus Ex, Dishonored, & Elder Scrolls.

The team at OtherSide helped invent this style of game with Ultima Underworld, System Shock, & Thief: The Dark Project. Now, they’re working to take it to the next level.

Enter a fully-realized dungeon realm where the narrative & world react to the player’s unique actions & decisions.



The Improvisation Engine provides a wide array of tools to experiment with & create your own ingenious solutions to challenges. Unlock your creative potential. Devise clever techniques that even the game’s designers haven’t imagined yet!


Become embroiled in an epic plot, as rival factions vie for dominance in struggles that ebb & flow across The Stygian Abyss. Which side will you join? Will you unite, or destroy?



Launch yourself into fluid, running battles where maneuvering & timing are everything. Utilize your environment to stack the odds in your favor.


Collect magical runes bristling with power. Combine them in startling ways with our procedural spell system.

More than just a dungeon crawl, Underworld Ascendant innovates ‘immersive sim’ gameplay in bold new ways!
