The map designs for KZ2 are the best map designs I have ever experienced in a MP game, everything is done amazingly well, and it is very balanced too. So I have no idea what youre talking about.
Killzone 2 is The Dark Night for video games. It was nominated for everything else, other than the actual award that it shouldve been nominated for, and that is the goty award.

Did COD MW2 have bosses in it??? This isnt Shadow of Colossus, its a fps war game. But it would be fine if they decided to add it though. And a co-op would be good although KZ2 was still amazing without it.
