I've made a list of keys that were found by GHFear and ssh so far (and some of them by myself). Some of them can be outdated though, especially for online and mobile games.
List of keys has been moved to rin forums, as well as older keys for previous versions of some games.

Gears 5 uses oodle compression for b2container.
The GearGame.b2index file contains information about B2 container names, file names, and their location and size in b2containers.
There should be localization texts in Launch.b2container.
Could someone create a bms script to unpack the files?

Key mentioned in post above: Breeders Of The Nephelym 0x2F0AF645DB48E847A58711EE2DD712E7B41789896F3B2AA23C2EF5427BE0F084

However not able to unpack with the script or with UEViewer...

Saw this as Steam store was highlighting this as a top 'User recommended games' lol. I can't unsee what I have seen in this game!

That's because they've updated the key. See new key in the list.

Thanks! that key does work. However with UE Viewer I can open and see the asset list but can't view or export them. Using QuickBMS I can unpack the assets but how do I go about extracting mesh and texture data from uasset files? Sorry for the basic question but I am used to just using UE Viewer for extracting...

Moons of Madness just came out and I've been waiting for it to do so. Can anyone decipher the AES key for it?

I suppose this question belongs to Umodel/UEViewer forum, since quickbms works fine with the game. Also, many latest UE4 games require manually forced engine version in umodel for it to work properly (explained in the FAQ).

It's not even encrypted.

Weird, BMS tells me it's encrypted. Do you have any advice for this?

Huh, strange, quickbms says Moons of Madness is encrypted, and errors without an AES key...
