At the start of the lvl you are in a whiteouts version of a house:
- remember the outline of the stuff in there
- find a interceptor.

then go throug the appeared door to the blackouts version of this stage:
- find the numbers for the padlog ( missing furniture or object tell you which part of the room contains a number)

after opening the door in the whiteouts go down the hallway and solve the fuze puzzle and enter the portal:

next you spawn at the blackoutsversion of the hallway:
- explore it and then go down the hallway and "solve" the "puzzle" ;)

after that you get to the whiteouts version of the "special puzzle" that doesnt require you doing the usual "find end use" stuff but to find the right way.
The whiteouts tell you the right way so remember it

in the Blackoutsversion you have to take the whiteouts way.


in the big Qube you have to collect all numbers and then go to the blackoutsversion of it.

on the blackouts verion you have some interceptors that are ordered like a keyboard numpad sooo i guess you know what you need to do with the numbers.
