Trivia: No One Lives Forever
- Franchise Killer: Contract J.A.C.K. was so bad that Monolith gave up on the series entirely because of it.
- Hey, It's That Sound! - The games reused the "objective-updated jingle" from Shogo: Mobile Armor Division, also made by Monolith.
- Hey, It's That Voice!:
- Keep Circulating the Tapes: Thanks to a complex series of acquisitions, mergers, and various other publisher mix-ups, no one actually knows who owns the rights to NOLF anymore, so the public is unlikely to see any kind of authorized re-release anytime soon.
- The Other Darrin: Cate Archer's voice actress was switched between the first and second games; in the second game, she's voiced by the very well known Jen Taylor.
- What Could Have Been - the entire reason the main character is female is that MGM/UA warned they would sue with the James Bond-like male secret agent Monolith had initially planned. The game was to be a straight spy thriller set in the 60's, with no humor involved.
