Before I buy it... is it useful?, what does it allows me, I mean how does it works?, for those who have it, is it really good to have, or should I wait and earn more skill pts to buy another thing?
I don't think its too helpfull either. I allways ask for the alibi first to make sure I get it. (but then on the harder levels, there is that guy who clams up and doesnt respond to sweet tlking.)
