Best Compression Methods for 'Specific' Games. Q&A

[L33THAK0R]

GOG Release - Build ID 57836190042333563

Original Size: 48.5 GiB
Final Size: 15.1 GiB (16,313,675,776 bytes) (Incl. installer)
Ripped Files: None.
Tools used:

Xtool v0.8.9 (Codecs: zlib) (reflate is a touch hit or miss with UE titles, so I opt to play it safe and rely on zlib)
Srep
Lolz
Oggre

Notes: Additional gains were made by patching audio post-install. Unreal Engine 4 titles, in regards to titles that use regular Vorbis OGG audio store it without exception within the "*.uexp" files, archives were first unpacked then using a basic (but fast) python script I threw together, a 10-byte string was searched for within each extracted "*.uexp", resulting in only 772 MiB of writes for an approx. 110 (+/- 10) MiB improvement over current leading results.

Honestly the real challenge was figuring out what I wanted to do for the game icon, I think it turned out alright but the art assets were surprisingly difficult to extend or frame so I went for a compromise using an asset from the official art book as a frame.

I don't want to clog up the forums so I might make a bulk post of the few hundred compressions I've done in the last couple months, but whilst they are quite impressive for the most part in terms of ratio, there's nothing really interesting or unique about the processing methods.
