If you haven't yet, go get yourself a copy of that amazing JKG mod! It's been a while since I've played and it feels like a whole new game! Definitly the most fun I've had in JKA for a while!
I saw this. It looks like a very serious TC mod with a very nice UI. I'm not much for MP shooters, but if they can incorporate RPG into it, I'll be all over it.
Put the assets in the JKG/base folder, run the exe. It doesn't need to be in your JKA directory, and probably isn't recommended either to avoid unexpected bugs
