If you're any sort of weapon tinkerer, I had to develop a lot of real world weapons for the
CORPS setting, and the ways I used the power design system to do it are what I condensed into the separate weapon design doc for
EABA v2.01. And it is worth a mention that this doc is a
free download over at the BTRC site, so anyone is welcome to download and play with it. The 15 page intro setting for
CORPS is also a freebie.
