First of all to become JC while playing the game is just start walking sideways to walk faster or if you are already a veteran just bunnyhop from place a to place b.
After you have learned the sidewalking or/and bunnyhopping you need to get a pair of black raybans, get lung cancer and go to the barber to get a haircut.

After those you need a long black leather coat and some black boots go get those from your dads closet and come back afterwards.

After doing all the steps of part 1. then you need to become a cold hearted killer that follows all orders and disregards his humanity and goes back to monke.
You speak like a robot with the same monotone voice with almost no facial movements and emotions even when there's a bomb A BOMB JC.

Now that you have become the real JC you can give this GUIDE a thumbs up or something so i can get some clout in steam.
