Soulkiller

Soulkiller is a Black Program written by Alt Cunningham, later stolen by Arasaka.

Background
Developed in a lab on the 120th floor of Arasaka Towers in 2013, the Soulkiller virus is a program capable of creating a digital emulation or copy of a netrunner's mind, utilizing an advanced matrix recorder storing it in a huge database. It then wipes the original personality away, leaving a mindless husk that eventually dies. Few mainframes in the world are capable of running the program, with the only mainframes running it present in Arasaka Towers in Night City, or in Tokyo.
