Perfect Dark Zero

This game does everything right. There is a nice selection of weapons that requires the player to think through whether s/he wants to swap a weapon or not, seeing that you are limited to two types of guns at any one point in the game. The graphics are great and the settings varied. I also like the direction indicator so you can keep moving throughout the game with the least frustration. My only question is where is the rumored Perfect Dark Zero 2 for the 360?
