9/10
For anyone who hasn't played yet, if there is one single thing I'd recommend and wish I had done - play the game on normal your first time. No matter how pro a gamer you are, the crushing difficulty radically changes the combat segments and you are pretty much forced to hide behind walls always whereas in normal you can flow through the environment in a much, much more natural way that is obviously how the game was designed to be play. Crushing just kills that though, and the game is way more fun in combat when you are flying on ropes and shooting and jumping around and using the entire environment, which you can't really do on crushing.
