A button combination in the popular shooter game Halo. Also known as the "Double-Shot", the RXR combination performs an instant kill if done correctly. This can only be done with the Battle Rifle. This 'cheat' is done by pressing the Right Trigger (R) to shoot, then X to reload, then R again to cancel the reload action and shoot a second time. The combination must be done very fast and precise in order for it to work. It may take a lot of practice to make it useful in your favor.
