Alright, I was playing practice to get used to the game and the only thing I couldn't figure out was how to level up skills. In the menu they say 1,2,3 etc. will level up skills or something but they didn't do anything when pressed. I played the first MNC on xbox and just recently got a pc so I don't know how to even play the game right. Anyway, if someone could just tell me how to level up skills so I don't waste too much time forgetting the obvious, I would be really grateful.
