Well after two playthroughs as Sneaky Mike, I was ready for a change and tried Rambo Mike.
Clearly sneaky is the way it's supposed to be played, but for laughs, I'd really go for Rambo.
Kicking in every door even when you could open it gently is wonderfull after all that pussyfooting in stealth mode.
However it does bring out the flaws in the AI. Guard are not quite up to dealing with all that agression I'm pooring out over them.
Furtermore it turns out something as simple as a door or a corner is enough to get them completly confused.
Mind you, I'm not talking run and gun Stupid Mike here, I"m talking tactical, line-up-those-crusshairs Mike. Given that most guard can see across a room at best as posted above, using your AR for long distance sniping is a bit of an exploit.
