10 Nations

The 10 Nations are a mysterious alien race that appear in Half-Life: Defense. They appear to be completely biologic in nature coming down to even down to their weapons. A few people appear to know about them like when the Investment Advisor says "The worms are coming!" meaning he possibly knows about the existence of the Gene Gene or Pit Work. General Adrian Physical Shephardt also encounters a Save Guard before fighting the Gene Gene rambling on about a "Good body". Whether this is related to the Gene Gene or any other 10 Nation creatures is unknown.
