With the new knowledge of how to bait the Klem, and the colonists evacuated from the surface aboard one of the Cutters, Max could focus on eliminating as many of the creatures as possible.
Using the Disruptors on higher output levels would leave large amounts of radiation in the air and soil, much like a nuclear explosion, but it decayed within hours, leaving very minimal lasting damage except on animals and the targets it hit. Max was considering doing precisely that and clearing the area down to bare soil, but the Klem wave was already thinning out in his area.
They were out of reinforcements that could be sent over, and both his sensors and the scans of the Drones showed that there wasn't another Klem to be found within fifty kilometres other than the ones that they were fighting here.
