Just another mission, or so you thought… until your asshole dad sent you a text saying you were a little gay before you became wanted by the US Government for going AWOL. Just when you thought you were finished, a man with gas mask offers you the chance for another beginning.
As everyone knows there's only a handful of things better than Half-Life. These things are the SAW from Opposing Force, the PCV from Opposing Force, and how the human grunts are better than the Combine in every way. And as much as I hate the Half-Life HD pack. I do have a soft spot for the HD RPG.
