This pack is no longer hosted here, as it is now a mod. The current version of the add-on can be found on this page:

[TACZ] FreeZBe Gunpack Addon

The add-on requires TacZ Mesh Loader [TML] for the correct display of weapon models!

The ZIP version was supported by the community, so it will continue to be released, albeit in a stripped-down form compared to the mod—meaning without the unique features.
