I played SPAZ. It is a fantastic game until the infected stuff showed up. Such a let down. It is about as bad as the flood in halo. I don't see why videogame developers feel they need to "mix it up" half way through the game by changing the gameplay so much that the entire game is different. I loved the large naval battles, but now I have to micro manage "infection" and tip toe around small bits of debris. Damn, I was really enjoying it too.
