I don't know, when my room mate and I played Perfect Dark Zero.... It was a rather terrible experience.
I think Perfect Dark Zero was at the same level as Haze. You didn't get lost as much in Haze, but Perfect Dark Zero has more interesting weapons and secondary fire modes. Haze also presented everything through the game, where you had to have LONG lulls between gameplay so the game can actually try and tell you what's going on.
