Hi How to create new forces that are here Force powers - Wookieepedia, the Star Wars Wiki
Hohohohohoho! Wow, so glad I swooped in 'fore anyone unleashed hell..
Case in point, you're looking at remixing the game code if you want new force powers. so unless you're looking to really work at it(which it doesn't sound like,) you're best off just daydreaming versus working weeks and months to make a new force power..
