Kristy Stevens pressed her cheek into the grooved stock of the DDY-12 Demolisher. The 300x maginifcation scope was lined up with the podium of the Grand Mediator. He was due in three minutes. She brushed her hand along the stock, moving it along until she reached the curve of the exoshell. Her body lay in a zero-gravity field. There was a faint pressure on her mind from the ionic-wave converger that allowed her to control the massive exosuit. A retinal display gave her information on the suit. Pressure stable. Footing stable. Rifle stable. Condition excellent. Placing her eye against the scope changed the display.

 She pushed herself away from the stock and floated in the zero G. So much had happened. This was it. To say she was staking her life for it would be wrong. She would definitely lose her life. No, she was staking all the lives that had already been lost on this shot. The automated defence system would fire a nuclear shell at her position as soon as her bullet's trajectory had been calculated. Not that she could move anyway. This one had been bolted to the ground, not like the others. The DDY-12 was too heavy, it pulled the exosuit down. Not even this three-story-tall robot could handle the gun without both of them being tied to the planet. Kristy looked at the control-stock inside the exoshell. It was almost laughable that such a thing controlled the gun outside, larger than a spaceship, and with more propulsive force than three. It needed every iota of strength. 
 
 She drifted back. There was movement. A small beep sounded in her ear as someone took position inside the scope. It was him. Her cheek felt the groove of the stock press harder against her. She took a breath. She let it go. This bullet would change the universe. Maus would see it. He would tell her that she had done good. She knew it. She pulled the trigger.
