must own for PS3, must rent for the hardcore

The level of polish is amazing on killzone 2. 
-The graphics are awesome!  period.
-Great UI, your always focused on the screen and not bars. 
-Great save system, You never have to replay a lot of the game 
-Bad enemies, there's not a lot of variety. your basically fighting the same guy over and over 
-good pacing. The game does its best to switch things up i.e. HALO  

if your reading this review then your probably a hardcore gamer and if you haven't played this game then stop what your doing and go play it!
