In the level "burglary interrupted", there should be two thugs at the start of the game. After you kill them, near the bank there will be an opening and you will see a basketball hoop. On top of one of the buildings, there should be a basketball. Press "square" to pick it up, and then toss it off the building. It should land on the street. Press "square" to pick it up again. Then press "square" to throw it at the hoop. Then if you aimed right at the basketball hoop, Spiderman will say "Nothing but net!" Then a health packet will appear under the hoop. This is useful if you get hurt during the thug fight.
