"Fireball" was the original weapon 8. It was a stronger type of blaster and looked better. It is available both powered up and unpowered up by using SCEs. See Stronghold: Jazz. (Overlord's site)

"Blade Gun" was the original weapon 9. It was a stronger type of blaster and looked better. It is not available except by people with the beta versions or Xtreme hackers. (Not sure about that last part)
