Gather the team into a conference room or other empty space and "lock" the door. Beforehand, select one team member to play the zombie — dead eyes, arms outstretched, muttering "braaaaiiiinnnnssss" and all. The volunteer zombie will be tied to the rope in the corner of the room, with 1 foot of leeway. Once the team exercise starts, every five minutes the rope restraining the hungry zombie is let out another foot. Soon, the zombie will be able to reach the living team members, who will need to solve a series of puzzles or clues to find the hidden key that will unlock the door and allow them to escape before it's too late.
