Trivia
- Before entering the work in-progress test chamber, Virgil says "generally they (test chambers) need to be tested at least three times before they're finalized. Some people just can't count further than that I guess". This is a reference to the running joke that Valve can't count to three.
- The track played during most of this chamber is called Transitional Period
