You freeze for an instant, and then raise your hands above your head slowly in a desperate attempt to save yourself by surrendering to the assassin. Unfortunately, your actions do not impress the cold-hearted murderer.
With horror you see the muzzle of his rifle spit a cone of yellow flame, and then an agonizing pain erupts in the middle of your forehead. The impact lifts your feet off the ground, sending you sprawling against the courthouse wall. The pain disappears to be replaced by a numbness that clouds your vision and drains the last of your strength from your unfeeling limbs. An overwhelming desire to sleep assails your senses, and, although you fight to stay awake, it is a fight you have no hope of winning.
Tragically, your life and your mission end here in Tombstone, Arizona.
