I've come to the realization that I have no idea what the Terminus' ships will be armed with. I was planning on just going with regular old laser/particle beams/plasma, but I feel like I'd be outclassed by everyone else by a [i]significant[/i] margin. 

Hmmm, maybe I'll go with something like with what the Reapers in Mass Effect have. Though I get the distinct feeling that molten metal accelerated to a significant fraction of the speed of light would do far more damage than just the big old lasers they appear to be in-game.
