Given my recent positive impressions of Hitman (2016), is it possible that I missed some fun assassination-puzzle gameplay in 2012's Hitman: Absolution?

Well let me put it this way: when you re-load a checkpoint, previously-killed goons respawn (reference 1, reference 2).

So, no. If Hitman: Absolution won't allow me to retry just my last move - instead resetting all of my stealth clean-up, which makes me wonder if I'm supposed to shoot my way through? - then I don't think I've missed much.

Progress: Gave up as soon as I was detected, and found out about this checkpoint garbage.
