If you know the passwords then Yes,you can.

I mean will there be open rooms/locations with the hints(passwords) to the moment of its appearance?

Sergey507
Not all of them. Access to some offers, for example, with a key that you had no time to take (without cheating)

Sergey507
In the first scenario, the Tyrant appears after you go through extinguished the helicopter. in the second scenario, when you went through the shower and got in and out the office STARS. All that managed to do the plot up to this point is all yours.

Sergey507
It seems that the time stops and nobody disturbs you until you twist the safe.

Sergey507
Yes, then it will be possible. When you go in the sewers, you can go back and access all that is.
