Additional Content

The Backrooms of Arx Fatalis

Description: "If you're not careful and no-clip out of reality in wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of moist carpet, the madness of mono-yellow, and endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in. God save you if you hear something wandering around nearby, because it sure as hell has heard you…"

Arx Better Balance Mod

Arx Extended Mod

Description: "The long term objective of this mod is to make the game a little less linear and add enough features to increase its replayability value. So far, there's only a number of NPCs affected but a lot of item related stuff in this mod. Eventually, most of Arx will be affected by this mod."

ModDB page | Nexus page | See the forum thread and readme file for a detailed list of changes.

Arx - Second Life Mod

Description: "I started this mod as improving of game balance, but it also contains graphical improvements, new weapons, new weapon crafting and other interesting things. It's not final version - it's still beta. In general, this mod makes game more interesting and little more difficult." - see link for details.

Instruction for installation and description of known bugs are in the readme file (which is in the archive).

Arx Enchant and Balance Mod

Description: This mod will add many new enchantments and rebalance Stealth and Casting penalites on weapons and armor.

Instant Level Change Mod

Description: With this mod you can go to another level by simply "walking" through the stairs, without having to click on the "change level" icon.

ℹ️  With newer Arx Libertatis versions you can achieve the same effect by setting the Quick level transition option under Control settings to Immediate

Lockpick Mod

Description: With this mod you can combine lockpicks with different values (durability) and create a new lockpick with the durability equal to the sum of the values from the other lockpicks (up to a maximum of 25). Examples:

  • 2 sets, one with 4 durability and one with 5 durability will result in a new 9 durability set
  • 3 sets, two with 10 durability and one with 4 durability will result in a new 24 durability set
  • 2 sets, one with 15 durability and one with 20 durability will result in a new 25 durability set and another one with 10 durability

To do this you just need to double-click one lockpick and then click on the other lockpick.
