Thanks for your reply.I have searched the solution for the game quiet a long time.The topic you mentioned above is also looked up for several times.Just can not find a way to sucessfully unpack the package. :oops:

I'm interested in extracting the assets for Britannic Patroness of the Mediterranean and I was wondering if the .exe files could help me find the AES key that I need to unlock it: https://mega.nz/folder/nW4hRL7A#PlwE3K3ZnJKUZt3cFpoYkA

@Puterboy1: You can find it in the list from my signature. Also I suggest you to try AES finder (also available via my signature) for future updates.

@Julayi: No game title, no sample, nothing? Anyway, if you can't find the game in the list from my signature, you're out of luck, since nobody is extracting aes keys from mobile games nowadays (at least for UE4 games), aside from very rare exceptions.

@Julayi: All mobile and desktop versions of pubg can be extracted with specified scripts, available in the post from my signature. Mobile and lite version are not encrypted, so only certain scripts are required, and the key for desktop version is also available in the list from my signature.

@Xray: Current ACC version is 1.4.4, so not sure what you're trying to unpack. Read my signature, you can find key for the latest version there (also compatible with a few previous versions). If you're trying to unpack some old build with different key, use AES finder to find the key.
In case if you don't need maps, just models, use umodel to extract corresponding stuff.

Script for chinese pubg mobile (aka "game for peace") added to base post: viewtopic.php?f=9&t=1005&p=56251#p56251
Note that ini files will be encrypted after extraction, since I don't have a proper key for the game. The rest of assets should be fine.

Hi guys!
Please help unpack Unreal Tournament 4.
I need gun models and textures from there.
I used umodel.exe, as soon as I tried, unpacking does not work at all. The error constantly flies.

Dead by Daylight Mobile key added to the list. Grabbed from version 3.7.20, but should be compatible with almost all previous versions as well.

Traha key added.
Update: Key for actual korean version (2.5.5) also added to the list. New key is also compatible with latest japanese version (1.3.6).
Update 2: It appeared that first key is for QoApp game version, so there are two positions in the list now - for playmarket version and qoapp version.

Bless Mobile key added to the list. Grabbed from v1.200.196675, but also compatible with few previous versions. Specific script for Bless Mobile is also added to UE4_bms_specific_scripts bundle (read my signature).

--------------------------------------

It would be nice if someone could test stuff with those asian games and create corresponding topics on Gildor's forum. Complete cache for those games is not available for public, so I tested only small paks included in apk.

@WollieWoltaz: Thanks for clarification. So playmarket and Qoapp versions has different keys.

I've added them both in main list now to avoid confusion (both of them are up-to-date, but for different versions). Previous post is also edited to reflect these changes.
