this game you have to use it in undetectable mode for example you knock out a guard and take his clothes and then you have to hide the body because if he finds your body you become a suspect and so it will be much easier for you here at the door where you have to enter you have to to be disguised as a security guard to make a security guard come to see what is going on you turn off the generator there is a generator in the fan area and the generator needs to be turned off and then he comes to see what happened why the generator is not working and during that time he you knock him out, drag him somewhere to shelter and take his clothes and then answer in a box and then you can go without problems but that's impossible because there are many and they all pass you at once and you take a step one place and if an alert is given no one to open the door
