Encrypted *.unity3d file ?

Post by rpopulik » Fri May 19, 2017 8:25 am

Hi there,
I've recently bought on Steam Hired Ops game. It's a standalone version of Contract Wars unity webplayer shooter. I bought this game because I wanted to work with its weapons models. I had no problems with extracting webplayer version assets before, but in webplayer version, I didn't have access to all game resource, only to these downloaded for game sessions. That's why I got standalone version. And generally, in this version I don't have problem with extracting game assets (in *unity3d format) except one folder, unfortunately the most important one, which contains all HQ weapons assets (mostly models and textures files I guess). This folder contains files which look like they are some kind of encrypted. I attached two files: sil_pbs4-lod.unity3d, which extracts with no problems, and ak74.unity3d, which is probably encrypted:
http://www.mediafire.com/file/jc3xd7w7q ... nity3d.zip

So - is there any way to decrypt or convert in other way the second file to make it readable by one of the known unity3d asset extractors ?

Thanks in advance for any help.

Thanks Man! :D You really made me happy. If you need help with modelling, texturing or animating, don't bother to write.

However unity quickmbs scritp doesn't extract unxored file too, I still can successfully use some of the other available tools (already did it :))
