Killstreak fabricator are received after a tour of two cities. Usually require 2 weapons of the last killstreak tier(eg. Professional kill streak kits require 2 specialised killstreak weapons), and robot parts(eg professional killstreak kits usually require 2-4 pristine robot parts, 6-8 battle worn robot parts.)
