I like the models but I'm not 100% sure how well they'll fit with the generally dieselpunk-in-space style of Freelancer. The aesthetic of the universe is more "you can smell the lubricating oil through your screen" than clean modern sci-fi.
Having some more clearly kinetic weapon models is a good thing that we definitely need, though. Most of our heavy weapons operate on magic energy handwavium; it'd be awesome to have some that augment the destructive power of things like antimatter and barely-contained fusion plasmas with a big kinetic shove out the door.
