Interesting, I never bothered to look it up.Barely remember any respawning enemies in the game, unless you ignored cameras and ended up triggering the alarm on every corner.
Weird, because LGS actually added options to edit enemy respawning and weapon degradation in their own official patch. Sadly by the time the patch was out I had already played the game. See here: https://www.systemshock.org/index.php?topic=12.0
Technically this is a cheat though, and it would be safe to assume it was added at the publisher's request when hundreds of players started mailing them letters with 'reee too hard where do i go half life is better quack 2 is better fix respawn now or else' written in blood.
