Hit by a whip

Focusing, I pulled the wide-eyes slaver up out of his hiding space. Then something hit me from behind, sending a stripe of searing pain up my back! I dropped him, the damnably lucky bastard falling safely onto the roof just across the gap. I was surrounded now; the pony I had missed before had come up behind me while I was focused on this new one, a whip clinched in her mouth that she wielded with hellish accuracy. With a crack of her whip, she knocked my assault rifle out of the air, the weapon sailing out over the cliff face the track was skirting. The SMG slaver had taken my moment of surprise to reload, and now grinned; in his mind, he had already killed me.
