[PC Unity] Mecha BREAK

[Sydie]

Hey guys!

I've got access to the MechaBREAK Playtest - it's still in beta.

While I'm waiting for the playtest I wanted to explore the game files.

The game is built on Unity, however it seems that the game archive files (assetBundle) are double encrypted.

First I've "decrypted" the files using this tool:

https://github.com/tge-was-taken/CC3Decrypt

It seems to work - I can see a proper UNITY header in the decrypted file.

Once I try to open the decrypted file I get a message in AssetStudio v0.18 - "Unsupported bundle file. UnityCN encryption was detected"

I don't know and I couldn't find any information about this UnityCN encryption and how to bypass it.

I tried opening some of the executables and in "GameAssembly.dll" I can see some mentions of AES and aes.dll

 

Here's the dll and assetbundle for testing purposes:

PS: I'm really happy that I found this site, because after zenhax and xentax shutdown it was a struggle. Thank you guys!

Thank you @ModernLuigi

I've tried both tools, however it seems that I will still need to provide the UnityCN decryption key.

Do you know where I can look for this key?

ask them in the <removed by moderator> for the key.
