After exiting Momma Bosco's lab you will be next to the Desoto, walk away from the screen down the alley towards Sal and press
to
use fire escsape.
You will now be on the roof with Satan, talk to Satan (
) and say the following dialog options:
- Go Mets! [1/2]
- Freelance Police! [2/2]
During these dialogs you will sneak behind Satan and interrupt his broadcast and the trophy will be yours.
