Better than silent assasain
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.
