Just realized the GOG Version of KQ2 (Old Version) is 2.1 but when i looked up a Walkthrough of KQ2 i noticed the Person is playing KQ2 2.2

Howcome GOG doesent have 2.2 of KQ2

It's likely due to whatever version Activision gave them to use. Many of which are probably pulled from illegal online website archives in the first place (as old Sierra destroyed its original backups). Not always from the various collections made over the years.

Apparently 2.2 is not much of a difference over 2.1, other than some MCGA fix.
