Update 4 - Hotfix Notes

Update 4 Hotfix Build Notes

Hi all,

We've just released a 1.5GB hotfix for Update 4 on PC!

Here's what changed:
  • Reduced the force used to move carried objects against obstructions in some cases that were causing the player to be pushed in the opposite direction (for example, you might have been lifted off the ground while stacking crates).
  • Some wooden platforms that were floating are once again grounded.
  • Improved reliability of dragging mechanics for dead bodies.
  • Helmeted enemies no longer have floating helmets upon death.
  • Various lights, bottles and torches no longer disappear based on player distance.
  • Various controller fixes related to switching focus during menu navigation and tooltips not appearing for armor slots.
  • Fixed issue where the button guide bar did not show up for the Rune Wheel when using a controller.
  • Fixed issue where the sound effects for the Dash skill would continuously play.
  • Fixed an issue causing a lever in Underswamp to be inaccessible.
    Additional bug fixes.

Thank you everyone for playing!

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

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. Interact with useful flora and physics-based traps. Encounter fantastic creatures like Lizard Men, opportunistic Outcasts, and fearsome Mind Cripplers – all with unique abilities that can be used to your advantage.

Tailor your skillset by combining more than 75 skills from three different archetypes (Combat, Stealth, Magic) that you can mix and match to develop a unique hero who is truly your own. Craft over a hundred different types of spells using the runic spell crafting system. The game sets the challenge, the solution is up to you.

Become embroiled in an epic plot, as rival factions vie for dominance in struggles that ebb and flow across the realm. The decisions you make have consequences on events and the world around you. Unique challenges, dynamic enemy spawning, variable Outcast-built structures and a degrading world state that varies enemy population provide a dynamic world to play through in many different ways.

Set out on more than 70 quests and numerous Side Bounties that reward you for avoiding detection, going unarmed and more, providing many opportunities to explore, replay and test unlimited strategies and playstyles.

Earn rewards and unlock skills through resourceful, unboxed gameplay and ingenious performance. Solve challenges in unique ways and push yourself to experiment.
