The Phaozon suit in this game isn't technological, but the result of the Power Suit being "Virally infected" by the Phazon-mutated Omega Pirate.
So that's a clear-cut case of the Power Sit just straight up eating something biological that it was exposed to to upgrade itself.
Edit: Zodi, you didn't post the "horror happens despite smart choices" examples in the thread.
@Raz: Consider that in a lot of situations, if smart choices were made there'd be no movie. There's a reason why slashers tend to go after drunken, horny, pot-smoking teens.
Though I do recall Halloween 4 where when word gets out that Michael Meyers is in town the general response is to not only protect his likely main target but to call the state troopers and form a mob to hunt him down and kill him. Didn't work out too hot, he got a couple of people, the state troopers took their sweet time getting into town, and the mob killed a dud due to mistaken identity but come the climax of the film the mob, the sheriff, and the state troopers converge on Michael's location and proceeded to dust the bitch.
