I'm trying to earn 'Engineer', which is to pass a level 3 times without using traps:
However, despite not activating a trap, I haven't made any progress in this achievement. The only reason I can think of is that something else I'm doing is counting as a 'trap', and therefore triggering the achievement detection.
Does picking up/using items, disposing of bodies (dumpster, ice box etc), or taking shortcuts (windows, ladders etc) count as 'traps' for the purposes of this achievement?
If not, what am I missing?
