the wands, etc. Other than that, they are just beat up versions of their former selves from the first film. Here are some obvious and subtle modifications done to the hero packs for GB2: The unique ribbon cable was replaced with regular Spectra Strip cable. The grey crank knobs were replaced with black ones (or simply painted). The V-hook on the gun mount was slightly angled forward on some packs (for ease of drawing). The LC-1 A.L.I.C.E. frames were replaced with LC-2 versions (painted black). Extra padding (commonly called "Super Straps") was added to the straps on some A.L.I.C.E. frames. The Legris banjos on the Neutrona Wand were replaced with Nycoil banjos. The packs were heavily weathered (not sure how intentional that was, though). The Ion Arm Cap was heavily weathered on most packs (this is useful in identifying different packs). The Ion Arm Rods were stripped of their black paint. The square Clippard elbow on the Ion Arm Cap was removed, and a hex elbow was installed on the Ion Arm itself. All the GB1 tubing was Clippard brand - GB2 used Nycoil and some Clippard. The socket head cap screws connecting the shell to the mother board were replaced with button head cap screws. The mesh inside of the N-filter was replaced with a white covering. The Semi-Hero packs in GB2 were a new addition to the packs used in filming. These packs were stripped-down versions of the heroes, merging constructional concepts from both the heroes and the stunt packs into a mid grade pack for wide shots. These packs were also constructed lighter for the actors. many of the metal parts from the Hero packs were cast in resin and attached to the shell, such as the HGA, injector tubes, beamline and filler tube. Other metal parts, such as the Ion Arm, Booster Tube (and frame), PPD, and N-Filter, were actually cast into the shell, much like the foam stunt packs from the first film. These packs also had fiberglass cast wands, instead of the metal ones from the first film. The GB2 foam stunt packs seem to have been built somewhat better than the GB1 foam stunt packs. The foam packs seem to be constructed the same way as the semi-heroes but instead of being cast as fiberglass, they were cast in foam instead. Once again, the Ion Arm, Booster Tube (and frame), PPD and N-Filter
