I'm posing this question because I feel like I need to redress the balance re. the whole stealth-attack dynamic and having to sneak to get into position for 'sneak-kills', basically because I've always very heavily criticised the changes made to the basic stealth attack of the Hitman franchise, and I feel I might have done the series an injustice by doing so.
I just want to say, hopefully to in some way redress the balance, that I've been playing Blood Money and although I still do miss being able to walk straight up to an AI and coolly wire it without having to crouch-sneak, the way the stealth-attack dynamic is contextualised in Blood Money has totally changed my mind with regards the whole crouch-sneak stealth-attack dynamic.
As a huge fan of this kind of gameplay I only hope that whatever similar dynamic that might be implemented for BioShock is closer to that of either Thief or the Hitman series (which I personally used to think of as a kind of Thief: 'Modern' Age ) than it is to that of say something like Manhunt (because manhunt really does suck).
The suggested combination of 'Sneaky Smasher' and 'Chameleon Skin' has made me think the stealth-attack dynamic in BioShock might be a lot like Manhunt (with Chameleon Skin standing in for Manhunt's shadows. The worries me a little, since Manhunt sneak-attack dynamic is way too repetitive— it's the same thing repeated over and over again. The only way in which it's context sensitive in any meaningful sense is basically the location of the shadow to hide in. With chameleon skin it seems you might instead carry that shadow with you and so can effectively hide anywhere at any time (I'm guessing).
With the Hitman series it's all context sensitive. You have to pick your moment and the location and sometime even manipulate the AIs into a certain position to perform the stealth attack, so the entire dynamic stays fresh and exciting more or less throughout.)
I thought I'd just add this, since I feel I've done the latest iteration of the Hitman series (Blood Money) an injustice by criticising the Hitman stealth-attack dynamic based purely on it's implementation in the previous incarnations of the game.
Edit: I'm guessing that if the functionality of Chameleon Skin is time-limited it might mix things up a bit, make it more exciting and more tactically challenging.
