What is happening with Half-Life 3 and Highguard? (Grubbsnax Premium 02)

I talk about Half-Life 3 and Highguard, so the headline isn't clickbait. And I think I have reasonably good news about both. I know all you Highguard stans will be glad to hear that. Each week on Grubbsnax, Grubb will answer questions about the industry from premium subscribers. Go to forum.giantbomb.com to ask a question (thread is on the premium message board).
