Zombie Apocalypse

The test tube containing a clear blue liquid virus accidentally slipped from the hand of the lab assistant and falls to the floor, shattering into thousands of pieces. Seconds later, the alarm sounds as the laboratory goes into automatic lock-down. But it was already too late, as the vapors are wafting throughout the building via the air conditioning. After falling where they stood, the workers slowly regain life. But not in human form. The virus has transformed them into mindless zombies. Somewhere in the lab complex is an antidote. With the help of your team, look for clues as to where it's kept. You have just one hour. Failure is not an option.
