Would anyone know how to extract Forza zips with compression method 22?

Here's an example zip:

Considering the minimum compressed size being 0x234 even if the uncompressed size is smaller, I suspect there is some encryption/obfuscation (dictionary?) involved.
offset, comp_size, uncomp_size:
Code:
0x0000002e 0x00000234 0x00000430
0x0000029c 0x00000234 0x000002ac

Encryption/obfuscation doesn't sound very good, I hope it gets figured out :)

There are some missing information in this topic.
Is it Forza 7?
For what platform? (and is this method 22 used on both the platforms?)
Do all the zip files use this method 22 or only few ones?

It's Forza Horizon 3, in the later updates they used method 22 on some of the zips (not all afaik, I don't have the dumped game files right now to check).

From PC, I don't know what method(s) the Xbox version uses but I presume the same since this is a console port.
