A technology that might or might not become practical sooner than railguns, Electrothermal-chemical technology could be considered an intermediary between gunpowder and electromagnetic ballistic propulsion, which is also limited by constraints in power storage and generation within modern technology, but not as much as a coilgun or railgun. This mod adds a bunch of infantry arms using such concept and common calibers like 9x19mm and 5.56x45mm, plus means to hand load such cartridges mostly with cannibalized parts from conventional rounds.
Furthermore it adds extra guns including some that may be awesome but impractical like one that is sort of like the “Saiga-12” of the Gilboa Snake, a double barrel magazine-fed automatic shotgun, plus subsonic loads for 5.56x45mm more or less inspired by the subsonic 5.45x39mm loads except more efficient by using tungsten and depleted uranium to cram as much mass as possible in the small volume of a 5.56mm round, two milspec coilguns with one capable of, with less efficiency, using nails and crafted flechettes, new professions that may be a bit OP despite costing at least 8 points, and two new scenarios with one including a very !FUN! start location worth not spoiling, and a few other things.
Thoughts, comments and criticisms always welcome.
