Bonus Objective Requirements:
15 Headshots
Find the Head of Security in 1 minute
No Lives Lost

The hardest part of finding the head of security in 1 minute. Time it, and if you are over quit and restart if you want to get all the bonus objectives (for the T4 award). He may spawn in three different locations. This is the easiest for the time. The others - the kitchen, and the floor above are much harder to get in the time and you may be better off restarting.
