Nosgoth - http://www.nosgoth.com/ is new multiplayer game by Psyonix and Square-Enix
This is new game in Legacy of Kain series and have good design and art style.
This game is in closed beta and using Unreal engine 3. Can we have it, for modding purposes.

When I try to open it with current version, there is error :
ERROR: assertion failed: CompressedChunks.Num()
FUE3ArchiveReader::FUE3ArchiveReader <- UnPackage::UnPackage:Arm_AssH.upk, ver=861/7, game=8000 <- UnPackage::LoadPackage:arm_assh.upk <- Main

Here is file example from CookedPCConsole :

Amazing find, didnt even know they were making another game in the nosgoth universe :o brings back memories

Just to let folks know, Gildor said on the russian forums that he wont be supporting this unless it comes out of closed beta

After release.

Hey there,

some weeks ago Nosgoth went into Open Beta and I'm currently developing an Armory webapp for it.

But I need a lot of icons and images out of the gamefiles to do that.

http://i-zed.net/u/Nosgoth.rar

The archive includes the executable and a log of the pkgtool files.
I could neither find any .u or .xxx files, nor a startup-int package.

The game is uncompressed and made with Unreal Engine 3.

Thank you in advance!

Hi.
Could you provide sample packages, please?

There you go:

http://i-zed.net/u/Nosgoth_samples.rar

It looks like this game has encrypted packages.

Interesting.. is it a proprietary encryption or a known one?

If it's still of any usage, here are the startup packages:
http://i-zed.net/u/Nosgoth_startup.rar

I spent an hour researching the code, but wasn't able to find any place where encryption/decryption performed. So I can't decrypt packages.

Do you need some sample like .exe file or anything?

Thanks, I have it already.

I'm having the same error when trying to extract Nosgoth upk files.

FUE3ArchiveReader::FUE3ArchiveReader <- UnPackage::UnPackage:Arm_AssH.upk, ver=861/7, game=8000 <- UnPackage::LoadPackage:arm_assh.upk <- Main

And now that the game was canceled, extracting the game files while they still exist would be a nice way to preserve the game content for making fan animations, fan games, remakes, etc.

Did anyone figure out how to make Umodel work for Nosgoth?

I tried it again using the latest version of decompress and extract, but I still get the same error:

Here is my progress so far, using offzip I was able to identify the offset list of the upk file:

- open input file: BCMPGame\CookedPCConsole\Armor_WingedVampire_Evolved_ARC_SF.upk
- zip data to check: 32 bytes
- zip windowBits: 15
- seek offset: 0x00000000 (0)

After that I tried to perform the extraction of that file using offzip but a bunch of dat files, a txt file, and an xxx file was created, and now I have no idea what to do with those files other then checking them in the hex editor (I did that but didn't find any clue).

And here are the files that I extracted: http://zenhax.com/download/file.php?id=2852

Here is the AES key and a tool using it in order to unpack the upks. Exporting files has a somewhat success but I hope it could be better now when files can be read. Would this help in order to be able to use UE Viewer for Nosgoth?

@hetsen: Latest umodel seems to work fine with decrypted upks (though I didn't test it much). If you mean integrating decryption function into umodel, it's quite bothersome and doesn't worth it.

Okay, the thing I was hoping for was to be able to extract the models complete with textures and such so it can be imported into UDK again without extra steps

@hetsen: Like I said, umodel works fine with both kind of meshes and textures if you'll open decrypted upks in it, so you can export them as usual. You just need to decrypt all upks with the tool you've linked and rename them afterward. For example, following batch will do the work, just place it with nosgoth_decrypt in the folder with upks:
Though it will delete all original upks and you'll need a lot of free space, since decryption tool also decompress files as well. Alternatively, you can run only the first string from the batch, move "unpacked" files somewhere and then run third string from the batch on them.

I got it working but it doesn't seem to find the textures for the static mesh stuff.. Well, except at handful of them. Maybe I'm dooing it wrong, I've got the tcf-files at the same location.

@hetsen: Apparently the game is using custom materials. You can take a look if they're linked to mesh by pressing "M" after opening the mesh. Also you can look at logs/warnings in cmd window for better understanding. Either way, such materials can be recreated only manually (if possible).

Yeah, when I press "M" all I get is

for example. I guess all I gotta do is to manually export all textures and test what goes on what or something.
