Escape from Tarkov seems to be using encrypted archives, but only for weapon files.
I was able to open everything else using Unity Assets Bundle Extractor.
I'd be grateful if somebody helped me unpack them.
Here's a sample: https://mega.nz/#!1YYn0D7C!gZVYq1g8YuS7 ... MlG1Nus2vE
Thanks in advance.

It's XORed with 0x47.

Thanks! Is there a way to decrypt it?
I know nothing about these things.

Use this little BMS script on both files. And after extract with AssetsBundleExtractor.

Code: Select all

encryption Xor "\x47"
get fSize Asize
get fName filename

log fName 0 fSize

Thank you.

I'd rather necro this for the context than make a new thread; I'm no expert so I can't be sure but they seem to have switched around the encryption by now, inevitably. Isolated archives can't be opened anymore, has anyone nailed down what they changed?

I really hope someone will look into this topic even after so many years and help me!
I tried to export the mesh "weapon_glock_glock_17_gen3_9x19_LOD0" using AssetsBundleExtractor_2.2stableb and got the error "Unable to read the mesh asset! (Unknowing asset format)". It doesn't matter if I choose "Export to .dae" or "Export to .obl".
This problem occurs not only with the Glock 17 mesh, but also when exporting meshes of any other weapon. All weapon modules and all textures are exported without problems.
I would appreciate any advice on how to get the weapon mesh.

Here are the bundle files that contain the Glock 17 mesh - https://mega.nz/folder/eZ4ghAhQ#Je0wKuxuuw9y0YDDTqC8rg
