Any release date for the Xen part? This is my first time through the OG HL so, I don't want to miss out!

I played for a couple hours today. Its a lot of fun and I can only imagine playing this soo many years ago for the first time and how groundbreaking it was/is. My first achievement was called "Brownian Movement" (http://en.wikipedia.org/wiki/Brownian_motion) after giving a scientist in the bathroom some toilet paper. Hahaha!

HEY WHY DO THEY CALL IT HALF-LIFE?!

BECAUSE YOU WAIT HALF YOUR LIFE FOR THE NEXT RELEASE AMIRITE AHAHRAHA!
