Keep Humanity Under Heel This Halloween With A Combine Costume Couple weeks back, we posted a creepy, creepy Half-Life 2/Tom Cruise video . Also absolutely brilliant , but still, creepy. Well, this week, as promised, the clip's creator has put the Combine Metro Cop costume up for sale on eBay, and boy, is it great . It's referenced wherever possible from Valve's own designs (eg they used a Russian gas mask for concept art? This uses a Russian gas mask), and is loaded with incidental details, right down to a Combine ID tag and a fully-functioning voice-changer, for that authentic, garbled Combine radio chatter.
