Walkthrough
There are two versions of this game that have different schedules. Switch to the indicated room at each listed time to capture the Augers.
Wait for the meter to turn red a second time after the Augers grab Megan in Hallway 1 at 16:46 (version 1) or 16:38 (version 2).
Do not immediately change the access code at 5:37 (version 1) or 5:40 (version 2). Allow it to remain at the current setting in order to capture the Augurs in the following scene in the Living Room. Change the code after this is accomplished.
