Skyhill SURVIVING with SECRET ENDING

Skyhill ... SECRET END!
SECRET ENDING GUIDE
Earning the secret ending Steam achievement takes time, effort, and a careful eye for passwords.
Because so much of Skyhill is randomly generated, we can't go into extreme detail where to find each code, but we can tell you what these codes are. Yes, the login and passwords are always the same.
HOW TO GET THE SECRET ENDING:
Naturally, you'll need to reach the 1st Floor. We recommend going for the regular ending, then stopping at the 1st Floor before escaping the building.
1. On the first floor, look for an active computer. Access the file called mv-17.com for more information. Type the file name into an internet browser to check out a real website.
2. The website is locked and requires the correct login and password. Both can be found while exploring the floors of SKYHILL. Input to access the mv-17 website:
L: AMADEUS5
P: ShATTEREDRealitY
3. When logged in, access project file B1G-83-0310M4. At the bottom of the file, you'll find an important password.
Access Code: mr.wgmthooh
4. Input this last password into the in-game computer with the "mv-17.com" document. You'll get another screen of experimental information.
5. Now that you've unlocked more backstory, the Secret Ending is available. Leave the building to complete the game and enjoy this alternate end.
