** Maybe they were goasts/ghosts possessing their own corpses? Or maybe goasts is a different thing entirely from ghosts

* FridgeBrilliance - In the machinima, when [[spoiler:the transformed Gordon Freeman]] yells "NO!", he makes the same pose he made the last time he said it (just before being stepped on by the next boss).
