The Thunderhead Lance is light-weight, cheap, and incredibly powerful, and only requires a Heavy Weapons License. In game-play this weapon appears to be a large light-saber with a starship serving as its handle. Any ship, aside from Vell-os craft, can arm at least one of these, and most of them can use four, making for a very powerful tool of close-in destruction. As you might expect, this weapon is most effective on a fast, nimble ship. Note that, unlike most other continuous beam weapons, the Thunderhead Lance involves no energy drain at all.
