Created by Dr. Hunsaker near the 3043, XA-3 was a drug intended to help harness the Direct Neural Interface (or DNI) and counter the sensory overload directly caused by the usage of the DNI. Like the DNI it is highly addictive which can lead to obsessive and dangerous behavior on the part of the afflicted individual. Overcoming the side effects of the addiction is only possible by discontinuing its usage and enduring an extensive and painful withdrawal symptom.[1]


  • The Enhanced Imaging system used by Clan ProtoMech pilots, which connects the pilots to the ProtoMech in a DNI-like manner, also requires drugs similar to XA-3.[1]
