so is killzone 3 a hard fps, or am i just a newb at fps

im not a big fan of fps, but i figured i would try one out so i bought killzone 3.  now is killzone 3 a harder fps or am i just not good cuz i played the game on easy and i was having difficulty towards the end, unless it has a feature where it changes the difficulty based on your ability like infamous.  other than the difficulty, it was pretty fun.  the story was a little dry in my opinion.  

 

EDIT:  i'm referring to the single player campaign.  i think i totaled 50 some deaths on easy.  now i played demon's souls and that game seemed easier to me than kz3.  maybe thats because i live for rpg's and action games.
