So, ue4 decrypt with key

Then add zlib precompressor, srep and lolz.

Devs were nasty and put videos inside the pak with compression and encryption. Sounds are also encrypted but you should just be able to patch the encrypted data out using QuickBMS + Unreal script to print a filelist which will give you the locations of the different sound banks.

Here is the file list, so you don't have to create this

Beware, the file is 300mb in size, so open it could take a while

You can use -f filter in quickbms so it will only list files that you want.

e.g.

QuickBMS -l -f *.pck <bms> <pak> >> filelist.txt

P.S. don't rip voiceovers entirely because game will crash without them. Just patch them out to speed lolz up.
