Good mechanists/undead horror mission. Even quite original. For me two biggest issues with this mission were: 1) too obscure and complicated objectives with vault and Amulet (ok, the last one is optional on lower difficulties) and 2) loot objective (loot is too scattered around the level - and it is major flaw of mission).
I doubt there is any cyberpunk-style missions. Only maybe some futuristic FMs like Sliptip's Kill Factory series (especially, Escape From the Planet of the Robots), or Spoonman's TSR-1000. Three Distinct Adventures by Cardia. Also, maybe, GORT's Rebellion of the Builder (hard, as I've heard).
Valky, I don't know much about Deus Ex style exactly (how it could be done in Thief) but colored lighting was implemented in Thief 2 and is in the lots of FMs for T2. Maybe I misunderstood you.

It's simply unproductive and feels toxic (actually I can say it also about peter_spy's own comment here, above mine). Overall it is good mission although being a bit rough. From my point the mission also sometimes feels a bit big for the sake of being big, but I was ...
