Killzone 3 is a true example of franchise mentality; the entire affair is constructed with that distinct “Triple A Franchise” shine, the whole nine yards players have seen on titles like Gears of War and Halo. This is a product with significant resources at its disposal, all the way down to a high profile voice cast.
Though the core game is deserving, the concept is simply not the equal of this treatment. From the opening cinematic to the grim, atmospheric music in the menus, the player is primed for a dark, compelling tale of war, but as the campaign begins it becomes immediately apparent that this will simply not materialize.
The unfortunate reality is that the Killzone universe is simply not interesting, or at least unexplored in an interesting way. No amount of pomp or franchise expense can elevate what is distinctly lacking conceptually.
