Detailed wiki reference, unknown patch
Version unknown · Older walkthrough. Check against your current objective.
This reference covers the computer phase rather than the full current objective sequence. The wiki enters YBL-1 through the northern hole, takes the left corridor and descends the stairs to level -2.
After the stairs, the reference turns left, then right into the main corridor. It places the communications room on the left beside the briefing room.
Interact with the old computer at the far end beside a lamp to load the data, then interact again to retrieve the floppy disk. This two-stage interaction is not visually checked in the current patch.
