Interloper

(HL1 Part 48) So, those "Controllers" (the floating brains) are somehow able to mind-control the Vortigaunts that are near them. I have no idea if the mind-control has something to do with those shiny purple restraints on their arms and neck or if that is something else, but the Vortigaunts seem to be more complex than I initially gave them credit for. The Vortigaunts in Black Mesa were probably just scared after being teleported into a strange place, but the Vortigaunts here in Xen seem to just be doing their thing and aren't even hostile toward Gordon, unless they are mind-controlled. Very interesting.
