Hi!

This game was developed by Vertigo Games and published by Tencent.
From the preview of .vpak files in Hex Editor, it can be seen that 3D model files are in .nif format, which is identical to BlackShot model file format.
Texture files are in .dds format and Audio files are in .wav.
WOZ probably uses the same engine as BlackShot does.
.nif model files can be viewed and exported using NifSkope or 3DSMAX with nif plugin.
However, unlike BlackShot, all the game assets of WOZ are compressed in these .vpak archives.

Any ideas?

Sample files:

https://drive.google.com/file/d/1KUCnTF ... AcDr2/view
https://drive.google.com/file/d/1J2QbbN ... QwI99/view

Thanks a lot!

It's a custom ZIP archive that uses "VPAK" instead of "PK\3\4" and doesn't have the "method" field.
The flag field is 1 and the first 10 bytes of each data is the same.

I even tried to check if that 16 bit field was method instead of flag but the "shrink" decompression fails so I don't know, maybe it's just another type of compression that I can't recognize.

I'm sorry for the late reply. Thank you for your effort.

This game is officially dead, but I found a private server client of this game (now this private server is dead as well). This private sever client has all the original game files extracted from the packages, so all the file assets are obtainable. The files are in .nif, which can be previewed using nifskope. The models and animations can be extracted using Noesis script, but it seems that the Noesis script is unable to load most of the idle and shooting animations of the weapons, other animations are fine.

I would share the client here: https://drive.google.com/file/d/1GKJCUt ... sp=sharing
