I have never played the game without the zapper. It does take a lot of getting used to. I play with the alpha button configuration because I don't like the zapper button setup. Once you get used to it I think it plays very smooth and accurate. The most difficult aspect of it is the reaction time to cycle weapons/reload or throw grenades, or melee attack since you have to reach on top of the contoller to do that. With practice it becomes pretty effortless. I hold it shooting with my left hand and have the right hand in the back on the control stick. I hold it out like a swat or spec ops person would hold their smg. Makes it easier to control that way. Try it out. I think it makes the game a lot more fun!!!
