I'm going to use cls-ue4d by Shegorat, but XTool unreal plugin should also do the decryption.

So, ue4 decrypt with key

0xE01312D26CAD1529142D3ACA6DB25D4091C1AAFE0C91E5DC104C36A768DB1E50

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.

Time: 00:12:51 (01:52:39)
Memory: 0.99 GB (0.99 GB)

100.0%
Errorlevel=0

Compressed 1 file, 43,688,470,495 => 88,344,833,239 bytes. Ratio 202.22%
Compression time: cpu 642.13 sec/real 1488.20 sec = 43%. Speed 29.36 mB/s
All OK

but i don't know, if use Diskpan GUI @cesar

xtool:c32mb:mue4,k0xE01312D26CAD1529142D3ACA6DB25D4091C1AAFE0C91E5DC104C36A768DB1E50,zlib

Not Work, only got 100.3% ( CMIIW )

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.

im not sure what or you did but i didnt get anywhere close to 30.8 GB my repack was 39.0 GB

i used this method:
ue4d:key=E01312D26CAD1529142D3ACA6DB25D4091C1AAFE0 C91E5DC104C36A768DB1E50+xtoolx+srep+lolz <- xtoolx in this cause was unreal.dll


thanks

Sigh. You have space symbol in AES key.
