Another 'Purple' Gun?
The ultimate over-kill assault weapon, the mighty battle-scarred Fusion Cannon is ready for any tour of duty. Charged up, by holding the trigger a bit longer, til near bursting with great globs of purple anti-matter, this charming challenger draws in daredevil dogfighters like moths to a flame - Fusion Power. Remember the reverse trigger that shoots upon release and not on depression of the trigger, and you will see an expanding wall of energy fill the mine shafts and clear the way.
Slow to get numerous shots off - this is a specialized weapon.
