That is interesting to know. I see you beat on Saboteur level without having to kill or stun anyone? That is very good. I tried it, using smoke bombs to distract a few guards, but I had a hard time getting past the two guards by the pile of boxes the workers are moving into the armory warehouse.
But I will try again.
I see by your in game picture that it can be done without killing or stunning anyone at the Saboteur level. I did notice if I poison any food or water, the people who drink it and die do not count against me.
I do miss the total point score system of the old DTS. It gave more feedback.
