The research base was a small fortress, with buried sensor lines spreading 100 meters from a triple fence of barbed wire; the fences, the middle of which was electrofied, were separated by a minefield. Guard towers reared up every 250 meters. Animals caused false alarms around the perimeter several times a week and sentries in a skimjeep routinelly checked the area, although not primed for trouble. It had its own antiaircraft defenses as well. It was however vulnerable to a ground attack, due to its isolation.
