X2 bonus material not included in x-superbox?

[Zakhal]

I bought x-superbox and installed the four german mods for X2 that it included (taxidriver etc). It was hard to understand them since the descriptions were in german etc but googletranslator helped.

I noticed that in the downloads section there is somthing called X2 bonuspack that was released 5 years ago. Should I install it too or is it allready included in the x-superbox?

EDIT:

Nevermind the bonus package is included with the x-superbox. I need to install it too.
