Here's a mod I made with Apoc'd, Apatcher, roadkill and a nice Hex-Editor. It is a personal testbed-mod and changes the game quite a bit, my initial idea was to remove things that annoyed or bothered me (like capturing alive Aliens) but turned out into a complete overhaul with almost every single weapon/unit/vehicle changed and/or replaced. I changed names, pics, stats, orders, diplomacy everything. It is exactly fitted to my personal taste, so there might be things that you don't like. If that's the case simply don't use the mod and maybe use it as a source of ideas only. I will not change anything and/or update this mod, it's a take-it or leave-it thing.
Readme is in the zip. Backup your APOCA folder before installing, just in case
Thanks to micah and all guys making tools for Xcom, especially j'ordos..... and everyone still playing XCom Apocalypse!
