The recent notification made Kevin realize that the longer he took to clear the floors, the more difficult they would become. Right now, the first floor had only one Overseer, but if he didn't hurry, there was a high chance of more spawning after ten minutes.
There were two ways for Kevin to proceed from here on. He could either continue using a stealthy approach or go in all guns blazing and clear out all enemy forces. Alerting all the machines would mean he would have to fight them all, and there was also the possibility of hostages being killed in the crossfire.
All Kevin needed to do to obtain passing grades, was to rescue a minimum of 20 hostages. However, each hostage death would deduct 50 points, which would make it immensely difficult to cross 500 points. He couldn't afford to lose too many hostages or the training would fail.
