CosmicGamer said:- Success by just a little and maybe the patrolling guards were a decoy and the real guards are in camouflage armor. Just an example.
- Success by more and maybe the "smart guy" only had this base as a decoy and was never here and there is nothing to find but a note in the safe that says "You'll never catch me".
- Success by a lot and maybe the "smart guy" let the characters bribe and get the uniforms but they actually have tracking and/or listening devices in them and... lots of possibilities.
I'm thinking this is a common enough trope when the adversary is some Brainiac computer.
HAL certainly led the boys down the primrose path with decoys. An old Star Trek episode featured M5 yanking down the trousers on even ol' Mr. Spock by some classic misdirection and sleight-of-er-circuit that got them to waste time. And then there was an old '60s chestnut, "Colossus: The Forbin Project," where the machine pursued world domination Skynet style while toying with its inventors.
Seems like the ol' fake-out and false gambit must be in the classic UNIVAC playbook.
