Hi!
I recently started to mess around with this game (mostly the backend server) and I was wondering if it was possible to extract those .pak files.
I do not see any magic for these pak files, but I can see using a hex editor the list of files inside that archive and even the contents of some files, such as PNG?

Could anyone take a look? I've attached a sample file found in the .obb file of the app.
I have other samples, but those are quite big (18mb, 66mb and 75mb): https://drive.google.com/open?id=1qnLdx ... triBN_glKu

Would definitely appreciate any help on unpacking those files, and maybe even repacking if possible?
Anyways, thanks for reading! :)

prestage.pak


It should be something very close to this, it works with the example file not sure if there are any variations in the others.

I only tried the unpack feature for now, and it works wonders, even on the other files!
Will try the repack feature soon! :D

Thank you very much for your time! :)
