Neon Abyss
Step 1: 7x bundle files (ignoring StandaloneWindows64) - Use UBT to decompress them, then recompress each bundle and make a patch for each. I ended up with ~16mb of HDiffZ patches in total. When decompressed, the game requires 2.3GB of disk space despite only being 1GB when compressed.
Step 2: Compress:
Code:
srep+lolz/$mp4=srep+zstd/$bank=srep+razor/$hdiffz=srep
Final Size: 250MB
