Killa is an aggressive boss on Interchange that patrols the main building. Killa earned his reputation back in the days of the Contract Wars, when he and his crew took over the ULTRA shopping mall. For most locals, that mask with the three stripes means death. For a select few, it's a reminder of wild dubstep parties somewhere on the city's edge.
