Portal: Reverb. In Portal: Reverb, you play as the first Test Subject in the ASHPD Testing Sequence after GLaDOS' little accident with the Enrichment Center on that fateful Bring Your Daughter to Work Day. Approximately one year has passed, and surviving workers have returned to the Laboratory, to find GLaDOS shut down due to the early installing of the Morality Core.* Eager to get back to work, and refill their databases with information on the Portal Device, they hire an untrained employee, Paul, to run your test. Inexperienced with the Aperture Laboratories' console, the test never goes as expected. About half-way through your test, GLaDOS is fully repaired, and is put back online. In many ways, the initial test went well, until the effects of a certain other facility researching Portal technologies causes a catastrophic event of epic proportions.
