I am finally getting around to playing the Half-Life 1 expansion games. As expected, this is more of the same. This time around playing as a security officer who is caught up in the Black Mesa incident. Once again, you are trying to get back to the surface. There aren't any new game play mechanics (that I can see), and aside from a couple of references to Freeman, the story here doesn't really tie into the main narrative. I'm not sure if I am supposed to be the same guy as Barney from Half-Life 2. This is a short game (not worth the $5 it normally sells for), but it's a good way to revisit the original Half-Life without a huge time commitment.
