Much to their dismay, what they found at the bottom of the stairs was not the experimental labs but a large sign reading [Biomatter Storage] and a destroyed door with a large number of angry-looking Klem warriors in the traditional configuration glaring at them, but keeping a careful distance from the door, where a number of bodies already lay.
The security system was keeping them from going upward, which was likely the only reason that the Hybrids on the upper levels had survived as long as they had. These Klem were ravenous, so it seemed that they had already used up all of the Biomass that was stored in the facility, and they were ready to move on.
