So, ALL the game files (except exes and dlls) turned out to be encrypted with something using xor.
Due to incomprehension of the game disassembling, I tried to brute-force the key and managed to reveal just a part of it.

After I use it on any file in the attachment, it really does decrypt a part:

Code:

encryption xor "\xBB\x0B\xFD\x7D\x4F\x22\x80\x29\x65\x35\x89\xC9\xA8\x6F\x63\x4A\xCC\x0A\xEC\x53\xDB\x1C\xC6\x86\x59\x6A\x57\x8D\x73\x6E\x4F\x5B\x5E\xC1\x7F\x1E\xB0\xB4\x9E\x09\x15\x8F\x82\x24\x01\x08\x80\x51\x93\x2D\x61\x29\x48\x99\x36\xC4\x96\x9F\x4C\x08\x81\xDA\x52\x1D\x6B\x80\x0F\x6E\xF4\xD9\x9C\x62\x18\xD4\xDA\x7E\x2C\x58\x6A\x2E"
get SIZE asize
get NAME basename
string NAME  = ".dec"
log NAME 0 SIZE

But now I seemed to reach the dead-end, because I don't have any idea of revealing the rest of the key (which seems to be quite long to be brute-forced).

P.S. Also, it looks like the different versions of this game use different keys - the one in the attachment is a retail one, which seems to differ from the Steam one, as far as I could see.
