Hey @valvesoftware, in Half-Life: Alyx, we see a child's drawing of a Metrocop holding a Stunstick. However, the Stunstick in this drawing is clearly of the HL2 design from 5 years after HL:A. Did this child see the future?

Boy, I really hope somebody got fired for that blunder!

Also, we can clearly trace back this drawing to the first Google image search result for "Metrocop". Rather than question the canonicity of Google existing in the Half-Life universe, I will instead use this opportunity to admonish this fictional child for flagrant plagiarism.
