Just because. This game is on par with the crappiness that was Perfect Dark Zero, they share a lot of the same faults.
I suspect Haze would have scored higher had it been released well before more recent FPS offerings. Probably earlier last year rather than early 2008.
It's fair to compare games of similar genres, but even then reviewers went a little too far in panning this game, I think. It's a 6 average whereas most places make it sound like it's utter crap dpwn in the 4 average.
It's definitely not worth $60 to me, but from what my other friends say, it's a blast in 4 player co-op, still fun to play the campaign in spurts, and the multiplayer works well. But, it should drop in price quickly, when it goes below CoD4's price it should be worth buying. Right now I'll rent it for co-op with friends.
