This controller features our own Halo 3 calibrated rapid fire mod on BOTH triggers! Dual wielding is now the next best thing! With this rapid fire, your weapons will increase drastically in speed and accuracy. Owning opponents has never been this easy, until now. We all know Halo is a game of milliseconds, so why limit yourself due to a bad controller design? With A and B relocated to the backside, you overall control and melee's will increase drastically. With a factory controller, you have to remove your thumb from the aiming thumb-stick to jump or melee. Obviously this causes a delay in your reaction, leaving you on the losing end of the battle. With these two buttons relocated to the back, you can now use them so your thumb always stays on the thumb-stick, leaving you delay free. On top of having no delay with a melee, you can easily lose your opponents making it harder for them to kill you. Quick Q & A. Q: What games do the rapid fire work for? A: Call of Duty 4: Modern Warfare Call of Duty: World at War Gears of War 2 Halo 3 Halo 3: ODST Left 4 Dead 2 Left 4 Dead Grand Theft Auto IV Rainbow Six Vegas 2 Q: How do I operate the rapid fire?

This controller is 100% legal and 100% undetectable.
