Unity Underground

There seems to be a disrepancy between the amount of skill points at max level (16) between this and the original. In my original playthrough my character has maxed several skills at 16, such as Sword 30, Mana 30, Casting 30, Defense 30, and even had points left to put Lore 20, Attack 19 and Acrobat 15. For comparison my Unity Underground character sheet looks like this: 

Hi  Kweepa, Thank You very much for this port. UW2 was my very first dungeon  crawler and in my mind since then. Thank you for the possibilty to play the ancestor again.

Now my problem. I’m using keyboard/mouse controls. Win11 machine. I can select the Sceptre of Restore Mana and get the green use/charge circle, but I can’t actually trigger its effect.

Switching to the inventory cancels the selection, clicking the mana flask does nothing, and dragging the sceptre onto it just drops the sceptre into the world.

Is there a keyboard/mouse input I’m missing for using charged magic items like sceptres/wands, or is this currently a KB/M bug?

Thx for your reply  

I have a problem with the Ironwit's quest, about his blueprint. I got both the red and the green potion, the red one poisonned me that's ok, but the green one did nothing... Actually I'm in 5th level and i got about 6 or 7   green potions and the same number of red ones, but none of the is a levitation potion...

It looks like none of all this potions are working... weird ! I did cast Identification on them, did nothing too... 

And I did never find the "Uus" rune to levitate or make great leap using the magic...  

You may already be aware of this but some signs are floating mid air. 

Hello Kweepa, i'm stuck at level 7. Somekind of bug. When i talk with goblins, they ask me to show them the necklace and after talking the goblin disapper. The problem is i'm currently in a cell. The goblin who ask me to give him something disapper. There no more goblin near. I'm stuck there. Thanks.

Hello Kweepa, what insane amount of work ! Thx for that !

I'd ask you about the current state of the game, I would like to know if the game is playable at this stage meaning, can it be finished and does it offer a good gameplay experience overall, or are there still things you need to improve?

Many thanks !

Fantastic — thank you so much for the amazingly quick response! 😊

I’ve now found UnityUnderground_Data\StreamingAssets\Textures and read the readme.txt inside the Textures folder.

I was curious, so I asked ChatGPT to walk me through exactly what would be needed to make an HD texture pack, and… unless I’m missing something, it actually sounds surprisingly straightforward:

1. Extract the original textures from the original Ultima Underworld files:
   • DATA\W64.TR → wall textures
   • DATA\F32.TR → floor/ceiling textures
   • DATA\DOORS.GR → door textures
2. Export all of them as PNGs, preserving their original order/index.
3. Batch-upscale the entire lot in Topaz Gigapixel, for example 4×, using a conservative enhancement setting — no generative redesigning or changing the artwork whatsoever, just enlarging/cleaning the original pixels while remaining faithful to the original textures.
4. Batch-rename the resulting PNGs according to the naming scheme already explained in the mod's Textures\readme.txt:
   • walls → wall000.png … wall209.png
   • floors → floor00.png … floor51.png
   • doors → door00.png … door12.png
   • and preserve the required animated variants, e.g. floor16a.png, floor16b.png, etc.
5. Drop the finished PNGs directly into UnityUnderground_Data\StreamingAssets\Textures
6. And, apparently, that's it. If I understood the readme correctly, there isn't even any need to rebuild/repack the original .TR or .GR archives: the port simply detects correctly named PNGs in that folder and uses them as texture overrides.

So this looks less like creating a conventional mod and more like a rather mechanical extract → batch upscale → batch rename → copy operation. ChatGPT could probably guide somebody through every single step and even generate the batch-renaming script in about five seconds. 😄

Unfortunately, I am absolutely not a modder, so although I can understand the procedure, I'd almost certainly find some spectacular way of turning every dungeon wall into a door and accidentally banishing the Avatar into the Windows desktop. 😂

But perhaps somebody else here has a little more experience — and more free time than the fantastic creator of this mod — and would be willing to give it a try?

Even somebody who has never made a mod before might be able to tackle this one with ChatGPT guiding them step by step.

It would be a wonderful final enhancement to an already magnificent project, letting many of us experience Ultima Underworld — in my case essentially for the first time — in probably the best form it has ever had.

Anyone tempted to take the challenge? 😁

Hi Kweepa — first, thank you for all the work you’ve put into Unity Underground. It is a wonderful way to revisit the game.

I saw your explanation that higher-resolution environment textures could emphasize the boxy geometry, and I understand why you prefer the current look. Would you consider allowing them as an optional feature rather than changing the default presentation?

At modern resolutions, the walls, floors, and ceilings are the one part that can visually clash with the excellent new 3D objects and characters. I’m imagining a conservative 2× or 4× enhancement that preserves the original palette, motifs, darkness, and tiled appearance—not photorealistic textures or a redesign of the levels.

Perhaps it could first be tested only on Level 1 as an A/B comparison. If you don’t want to create or maintain an HD pack yourself, an even better solution might be a documented loose-texture override folder so the community can experiment and provide an optional pack.

The original textures could remain the default, preserving your artistic intent, while interested players could choose the alternative.

Thanks for considering it.

One thing I noticed as a mage, I can not see my mana while fighting. The health potion bar thing is there, but mana only visible when pressing Q, but then it disappears again when moving.

uhm.. why is this thing free at all? anyways. this is brilliant. I had the GOG copy in my folder for years, but now this helps me to dig in with minimal effort! I am having a great time so far on level one, using a printed copy of the original hand drawn map and the player's guide! 

i was wondering, since your project is based on the unity engine, is it possible to implement some networking for some basic coop gaming?

Thank you again for this great modernisation of a classic !!!

One thing I'd fixup is moving items around with the controller. It's a little weird. If you move an item over another item it should just push all the other items over unless it's a bag but with the mouse you need to go in between items and it works (or before the first item to move it to the first place) but with the controller it's just a little messy. I would just have it if you move it to a place everything moves over and no need for the in between places. Probably not too hard to patch that one up and who knows maybe people like it how it is. I just switch to the mouse to move things around but for some people who don't have that option it could be weird. Got to level 3 finally yesterday. Will keep going down the abyss.

So fun!

I am trying to refuel the lantern with oil, but can’t seem to get it working. Clicking to lantern doesn’t work. Dragging the oil over doesn’t work, dragging the lantern doesn’t work. Clicking the oil doesn’t work. I’m out of ideas :(

Thank you for all the work on the engine recreation. Currently playing it side by side with the original for comparison. Great work on the interface, feels very intuitive. I do miss the Wanderer music from the score, which plays a lot of the time in the original, and I don't seem to hear it much or maybe at all in Unity Underground (?) - any chance you could add it in again to recreate the score of the original?

I think there is a bug with the stew on level 1... When I get the scroll I can't read it from my inventory and when I talk to Lanugo he keeps telling me "It's all written down on this..." and claims to give it to be over and over and it never actually appeared in his bartering menu. A scroll does appear in my inventory you can't read it and when you use it it just says can't make recepie. He tells you what you need for it but nothing about a green mushroom so I presume you should be able to read that scroll. Not sure if anyone else had this problem also.

BTW awesome remake. I'm happy this exists.

Hi there.

Are the hold cheat codes still alive ? (F10 + a certain key)

Jumping seems laggy and awkward. Is that by design, or I am I doing something wrong?

No doubt you hear this a lot, approach gog to get it on that platform! Brilliant!

Any way to remap the controls?  The original Underworld has W X S A D layout, with X being backwards, S being walk, W being run.

Old habits don't allow me to use S as backwards, to this day.

Is there a control sheet? Or how do I bring it up in Unity Underworld?

Thank you so much for this. I love the game and your remake. Incredible! There are just a couple of details I'd ask you to add in your next version, if possible: 1) Add an exit to desktop button, 2) add the walking effect the original game had while moving. Thanks!

You should enable donations. I want to throw money at you.

Hello! Would it be okay if I create and publicly release an unofficial Korean translation patch for Unity Undergrounds?

The patch would contain only the translated files and would not include any original game assets. I would, of course, clearly credit you and the project.

Please let me know if there are any conditions I should follow. Thank you!

Hey, I have a quick question about the general mechanics of the game. Does it have a time limit? I remember reading somewhere recently that it has a time limit of a month in game time where the princess will be killed. Thing is, I cannot for the life of me find that source again after SO much searching. Is this the case?

This is fantastic, thank you so much for concentrating on controllers. I was using the other Unity port and messing around with mapping keys to the controller through Steam. It was not nice...

Are there any plans on UI scaling?

Looking forward to Hold too, good luck :)

EDIT: Quick question, is there another way of quitting, or is Alt-F4 the only way? Am I being super dense and missing something? (This is the most likely answer).

Il es possible d'ajouter la version française pour ce jeux ?

This is great. Never got to play either UW1 or UW2 back in the day, went straight for Daggerfall. Most likely because of the demo from the PC Gamer disc that was included with the magazine; I had hardly heard of Ultima back then (wasn't an avid gamer on pc yet.) By the way, is there any chance of the various types of attacks (bash, slash, stab) for all weapons returning?

It's wonderful to relive these memories of playing this PC classic.

Your hard work is greatly appreciated, and perhaps one day we'll see Ultima Underworld II here as well.

First, it's glorious and a dream come true. I do have to wonder if we'll see you take what you've done here and tackle UU2? Sorry if you've already addressed this elsewhere

Hello there, I'm dealing with a couple issues that I could use some help with, & I'd also like to request a couple quality of life features.

When I first set this up, I tried installing it the same way I did Daggerfall Unity; extracting everything into the Ultima Underworld folder itself. But when I clicked the executable, & it asked me to direct it to the installation folder, I hit the auto search button; but instead of the folder path the the GOG Ultima Underworld install folder was in, it found a path that included one of my "LocalLow" folders. It still worked, but the game was windowed, & I haven't been able to change it; I tried uninstalling & reinstalling it to force it to look for the installation folder again, but that didn't work.

That's why I'd like to request just two things; the first's a way to reset the pathing so you can set it to the correct path, & the second is a configuration option that makes it easier to set it to fullscreen & the proper resolution.

Hi, are you going to open source this project in the future ? I don't mind if you keep it closed source though.

Works wonderfully, any plans for the sequel if it hasn't already been made?

First of all - thank you! Many people have tried remastering Ultima Underworld it since early 2000s, but only you have had enough perseverance to do it.  This said, since it's Unity-based, can we have a Mac build as well?
