Turn on via Brucie for $5000.
For 60 seconds, your character becomes shirtless (or only in a sports bra) and is immune to bullets. You can only attack with the sloppy hand-to-hand punches and kicks.
I think it would be awesome to be able to turn this on and run into any type of shootout between other players or use against cops that have you pinned down or in survival. Plus it would look ridiculous.
