Encrypted *.unity3d file ?

[rpopulik]

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/jc3xd7w7qm65and/unity3d.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.
