: make sure that girl dressed in white isn't in the elevator room. She is the one who triggers the alarm so if she's not there you don't need to take care of the elevator room at all. Otherwise, if you can, tie her.Yell around
: when you shot all the cameras before the countdown, yell at the civilians in reception first, make sure all of them are on the ground. Then run to the north corridor and yell at everyone. If you can, yell at the civilians in the cafeteria abit. Then return in reception and so on...
Make the bots go around, they can help you in the first part.First phone call
: after the first telephone call, the bots automatically start going into reception and camping behind the desk all the time. So you don't need to take care of reception anymore, the only thing you need to do is staying at north corridor and yell at the cafeteria sometimes. If you want help, just yell at one of the bots and they will come (do NOT yell at one bot repeatedly. Every yell just freezes the bot by half a second, and that's what most players do all the time making them stand still and complaining on how stupid they are). Remember that when you start yelling at them, they will switch the gun into an Amcar.Guard
: wait for the guard to show up and melee him as soon as he get upstairs (unless you have a silenced gun so you can kill him faster). Do NOT let the bot come to you while doing that, it will shoot the guard with Amcar and set off the alarm.Repairman and civilians
: very simple, if they will appear yell at them, then go back to north corridor and yell, then to the other civilians and yell, and so on. With civilians coming from the elevator the stealth will become harder to do, especially when doing the patient files part.Patient files
: when it's time to search for the files, let the bot reach north corridor so he can take care of the civs while you are searching for the files. Remember, 1-2 files each, then go back to north corridor, yell and make the bot stay there.Sentry guns
: be careful, civilians can still trigger the alarm even if it's time to put fake sentry guns. Use your bots.
The rest is very simple, listen to the doctor and then cut the right wire.
