We all have a long list of games we adore.  But were there any levels in these great games that you absolutely hated? A level that was down right shit,  made you almost rage quit or just completely broke the flow of the game and made you go WTF. 

 

One for me was a level in battlefield 3 where you had to snipe a guy escaping in a car.  If you missed you had to go back like 2 mins and try again. I gave up trying to do it after 20 attempts and only completed it like a year later when I went back.  

 

So what levels did you hate in games you loved?
