Jack of All Trades seems to be horribly glitched for me. I'm looking at my completely Play Styles and some I'm sure I would have, I don't. Played the whole game on hard too.
Undertaker, Sandman, Bartender, Brutus, and even Needler Pumper. Think I should have Pitcher and Spook too.
Info on this?
[Edit]: So I've run around doing some strange things and some of these are unlocking for different things. For example, I grabbed a knife in Chinatown and started throwing it at cops and picking it up off them. After 5 kills I got Brutus.
I'd also like to add some input for the road map. I have about 15 hours, 50 minutes played and I'm close to finishing this. I think the approx. time is closer to 20 hours. It also seems easier than a 7. Just my opinion.
