At a convention in November 2011, a fan of Command & Conquer: Tiberian Sun (1999) greeted Michael Biehn by addressing him as "Michael McNeil, GDI, Tiberian Sun". Biehn was puzzled by the allusion, having no memory of that role until the fan described Tiberian Sun in greater detail, at which point Biehn, just beginning to remember that role, admitted that the 1990s were a big blur in his memory.
When Slavik is told to hunt for Jake McNeil, CABAL says "I believe you know his brother." This is a double meaning. Not only is Jake the brother of Michael McNeil, Slavik's opposite number, but Daniel Kucan who plays him, is the brother of Joseph D. Kucan who plays Slavik's boss Kane.
