Screenshots
History
This weapon has many applications. A magical weapon for Dark Star, an Ion Cannon for any of the Star Wars mods, and so on. As you can see from the screenshots, it's more of a crackle-and-spark impact than a lightning-ripples-along-the-hull weapon. Yes, when you charge up a dust cloud with ion beams and fly through it there is that nifty hull-hugging lightning. Unfortunately that effect is not controlled by EBG files, so an EBG file can't contain it. Alas, maybe in Homeworld 2.
