Tought I had to lure him to were you initially spawn using fast travel (where he says: I hope this isnt a bad idea, instead of the guard) or some other vent that you slide thru. The kill while riding the elevator was much harder - got him injured and then he hid under his office. Kept riding between B1 and B3 and eventually nailed one shot to the head thru a tiny gap. Wish I hadn't disabled kill cam to see that shit again.
