on some missions you have to beat up some thugs. before you do this, get the upgrade were you can grapple someone, jump up in the air turn upside down and hit the baddies head on the ground. knock out all the baddies but one, and grapple the last one. go to the empire state building, and charge your jump and let go. then, spin a web, charge jump again and let go. keep doing this till you get to the top (might take some time) then jump of (sprint jump) and press circle. you will turn upside down and go whizzing down. don't spin a web, it will ruin the fun. instead just hit the ground. the best part is you won't get hurt at all just the baddie! it's well cool. p.s works anywhere else but empire state is best because it's highest.
