well I love Half-Life, and I dont have tons of time to play it, so i dont mind if its short or not. I Know that there is a HL2: Wrath of the Yindor comeing out soon next year I believe.
This is what I read somewhere:
Half-Life 2: Wrath of the Yindor, will also go deeper into the Separation storyline, but not as Gordon, Walter, Adrian or Barney this time but as a yet unknown scientist working at the last surviving colony on earth 35 years after the disaster, almost every human being has been killed or converted to the Xen Race and the last survivors escaped to a secret Antarctic Research Facility known as IceWolf, thinking that the fragile Xen lifeforms would freeze in the cold, you, a 30 year old scientist, were wrong, the first adapted lifeforms start to appear near IceWolf and are starting to enter the base perimeter, after a while the power cables have been chewed through by the adapted Xenomes and now they are entering the cold facility... after you and the rest of the survivors. With a XenoFormed home-planet and your last hope destroyed you and your colleagues start the portal once more...
