10. Disguises
In the previous Hitman games, disguises were a vital part of getting about the open world, allowing you to sneak past the NPCs with the utmost ease to assassinate your target. In Absolution, however, disguises have basically been rendered transparent, and therefore rather pointless. Basically, if someone wearing the same uniform sees you, the uniform doesn't work, and you'll be outed in seconds, even if you slam on the instinct button to try and hide your face. This is apparently to promote the player frequently changing disguises, but it mostly makes for a frustrating experience that means assuming someone else's identity really isn't that fun anymore. Also, some disguise mechanics just plain don't make sense; you can be wearing a mask and the NPCs will still realise that you're an imposter, which of course, is completely dumb. Still, the Hitman mod community has already started releasing patches that means the NPCs don't look at you so meticulously, which feels more in line with classic Hitman.
