We found the code to open cafeteria door and when we walked through it, we fell off the map. Don't know if that's deliberate. We can't figure out the computer login code. We're typing the right command, got the full name using the list of the crew, and have the photograph that has a date but no combination of the numbers is working. Hoping you could help us out if we missed something. We really like the setting and atmosphere. Searching and exploring is fluid and fun. Also the double jump to get into vents works great and was easy to use. First person games can have some frustrating mechanics to move vertically but this was executed brilliantly.
