Picked this up recently for the PS3 and am digging it. Huge amounts of screen tearing but regardless, the atmosphere is great.
I was curious if anyone else found trying to go the non-lethal route incredibly challenging? I keep ending up in situations where I accidentally alert guards and have no choice but to fight (falling accidentally when blink drops me somewhere less than ideal, having the R2 choke hold miss so instead I block into their back and alert them, etc.).
Cheers
