Did you play Dishonored before??? I really didnt like it and returned it after 1 day. I hate games where you have to use skills that change the graphics completely in order to see the enemies and that becomes 90% of the gameplay.
I played and beat it on release (360) but have never owned it,
enjoyed it a lot. I haven't played it in a long time but I don't remember using any skill that changes the graphics for 90% of the time or really at all.
What skills were you using?
