Raine's Analysis would note that all of the enemies were robotic in nature, due to the extreme level of cold within the chamber. A series of ballistas were mounted along the walls, and the floor was occupied by automotons that swept the parameters of the containment facility on a regular basis.

Furthermore, they were attracted to heat. Good thing that there weren't any other heat sources within range.

The defenses and barriers that had been set in place were good, because the drones were fully live, now-- the first wave swarmed the group, firing steel-typed munitions at will. The rumbling sounds echoing from the back of the chamber indicated that ballistas were arming themselves, preparing to fire sooner rather than later.
