Game Night!: This weekend! https://www.facebook.com/events/317792721696252/
Playing as Colonel Shepherd (one of the soldiers) showed the best alternate point of view of what went down at the Black Mesa facility. It was fun playing as a soldier and to get to see what the G-man says to you in this game. Also you get to hear Freeman's progress at certain points during the event.
