Hello everyone, Im really interested in modding games on Unreal Engine 3, expecialy Batman Arkham City. What I want, is open Package file called 'Playable_Batman_Year_One_SF' by UDK Editor (Unreal Development Kit). The problem is, I can't open it correctly. It always say Load Error. I know what reason is, these files are protect and encrypted. My goal is decrypt them via HEX EDITOR, but I don't know how to do.

Looking forward to help, step by step. :D

Try to use the unpacker from Injustice 2. That does the decryption of .UPK/.UND files.

I know for a fact you can unpack this game because I have already have. That was about 2 years ago though so not sure how I did it.
