This game is about you, escaping as a scientist from Black Mesa Headquarter, A new building build in 1956. This building we're used to hold some public project. Before you joined as a scientist, you need to do a training on a Hazard Course. The Black Mesa Headquarter is much the same as Black Mesa Research Facility itself.
