Games like Splinter Cell and Manhunt require you to not be seen. This game series is overall, in my opinion, better than both of those titles. Why?

Donning disguises takes time, sure; you still have to kill / subdue your subject to get their clothes. But this game REQUIRES you to walk right past enemies and hope to God you're not suspected.

The adreneline will pump vigourously through your vains as you once again must sneak right past enemy faces in order to kill one or two marked men.you can impersonate someone else when you find a disguise and make a quick killing an go before they find out it was you.
