Although we may never get to see the real Half-Life 2: Episode 3 or Half-Life 3, we can continue scouring the games we do have for more details. That's exactly what Youtuber Shesez has done in the latest episode of his regular series, Boundary Break.

It may not offer details about who the G-Man is, but Half-Life 2 does have a number of interesting things hidden beyond its boundaries. For one, the intro scene in which the G-Man appears use actual 3D renders of past Half-Life locations, which are located within the game's world (though far out of reach for most players). For more details like where the skies in Half-Life 2 actually are, what happens to the G-Man between his sightings in-game, and where Dr. Wallace Breen actually is when he address you in City 17, watch the video below.
