Hello, everyone. Thanks to @vitt0x_Lar_YT releasing the passcode for the MediEvil-related package encryptions, we are able to decompile the demo PKG and UE4 PAK files with relative ease. Doing this, I found the following stuffs, take a look:
"Project Overbite" was the codename for the project. OVERBITE-PS4-Shipping-ALL-Demo 31 (Built 08/24/2019 at 20:30 From CL 20457)
The demo disc contains multiple non-final cutscenes left on the disc. See below.
I can't decrypt the EBOOT.BIN for further analysis, but we can unpack the PAK file. These files are then all in usual UE4 formats (but many don't open properly), and audio is in Wwise `.wem` format.
I'm zipping + uploading the extracted files to my server now but the demo is like 15GB so this will take a bit.
Thanks for sharing Sam! We've been reversing the full game on the Discord as well and will hopefully have some stuff to share here too (we do already have a DL for the unpacked pkg). You're also welcome to join us on the Discord if you like.
