Bugs and Mistakes

Ultima Underworld I inaccuracies [English | German] can be found at Hacki's Ultima Page [English | German].


You can find Ultima Underworld I sections of websites:


My Lizardman Language page contains a dictionary showing Lizardman to English words, and a translator tool useful for quickly translating Lizardman text.


"Life Off the Grid, Part 1: Making Ultima Underworld" is a detailed account of the dynamics involved in the development of Ultima Underworld, including the background of those involved, technological breakthroughs, and a rough but ultimately fruitful relationship with Origin.


The Ultima Underworld I manual, "Memoires of Cabirus", can be found:

A picture of an early version of "Memoirs of Cabirus" can be found at Pix's Origin Adventures.



In the southwest corner of Level 6, there is "an upset spectre named Warren", clearly an easter egg for Warren Spector, the producer of Ultima Underworld.

F10 Cheats

Some sites report that you can use four key combinations starting with F10 in order to enable god mode, add more light, skip levels, and stop time. These don't seem to work (mainly because F10 is the shortcut that makes you rest), and are most likely fake.

Unlimited Light

Delete or rename the SHADES.DAT file, and you will never be in darkness again.

Unlimited Scrolls and Potions

Use a fireball spell on a scroll or potion. This reduces them to debris, but they do not use their power. You can then use them as much as you like without them ever getting consumed.


The Digital Antiquarian has written "Life Off the Grid, Part 2: Playing Ultima Underworld", a detailed account of Ultima Underworld's gameplay and why it was so groundbreaking for its time.

The game's gameplay is demonstrated by a Japanese commercial [YouTube video] which was recovered and uploaded by Dominus Dragon.

Crowley provided annotated maps [ZIP] with locations of all magical equipment in Ultima Underworld 1, with the following information:

Crowley writes: Armor can be enchanted for increased toughness or protection, and weapons for damage or accuracy. These have the following levels:
Very Great
I used some abbreviations on the maps but those should be easily understandable. I have no idea about any numerical values associated, so I can't really say if for example a Dagger of Very Great Damage does more damage than a non-magical longsword. In addition there are a few magical items that cause the spell effect their name implies when worn, and those are rather self-explanatory. Perhaps the most obscure one is the Crown of Maze Navigation on level 7. There is a maze on that same level where stepping in the wrong place causes instant death. Wearing the crown shows the safe path. Also there is cursed armor and rings which cause damage when worn, but I didn't list those.
