Probably best to just go through the list one by one!
1- There are no scripts or blueprints included in the Military Weapons Silver pack.
2- The Packages includes models, materials, textures, animations, particle effects, and sounds for each weapon.
3- There are fire and reload animations included for each weapon but no hands are included in this pack.
4- This pack is compatible with the First Person Shooter BP template. However the package does not include hands, so users will need to create their own set of hands or modify the First Person Shooter BP template to remove the default weapon from the hands.
