I don't know the engine that the game was built on, so i have no idea if there is a similar storage theme on the archives.
What i've found so far:
Some bundlexmls are defined at the start of any archive which contain data about the rest of the files in the archive, so i guess these have to be parsed first and i'll try to do that tomorrow. These xml files are zlib compressed.
I'm attaching 2 sample xmls i managed to decompress.

There are also some .embb files which contain some names in there, have not checked it yet how they are used.
I'm excited to be honest, because i can clearly see some .mat some .mesh some .skel files which i'll investigate tomorrow.
