In the PlayStation 2 version, an Easter egg was added involving the two scientists occupying the toilet stalls in the locker room. It should be also noted that Brett's locker is next to Gordon's. It was later moved to Gordon's locker by another designer, most likely by Brett Johnson, the creator of the map.
According to Harry Teasley, the baby in the photo is his daughter, Isabel Teasley, and was originally placed on a broken desk in a ruined office. Gordon Freeman's locker contains a couple of Easter eggs: a photo of a baby, and two books by Marc Laidlaw, The Orchid Eater and The 37th Mandala (a texture for The Third Force was created, but left unused). The developers are also mentioned in announcements. There are also unused names in the files (see the List of minor Black Mesa employees for the names). The names of the developers can be found on the lockers.
