The Drop system is the main mechanic and its easily the worst part of this game; and when the main gimmick of your game is so bad i dont wanna use it, its not a good game. Flow-motion was in its infancy and it shows. Its incredibly overpowered here and there is no reason to not just fly around the map the whole time. I have finished this game exactly once. Unlike the other games in this series, I just cant go back to it.
