Well, You are the "GUS". Which is a plumber in Black Mesa. You have been requested. But Something in this Facitily is going and went wrong. After the "Resonance Cascade" Looks like Black Mesa wanted much more workers. Army is here! Make your way out of the Black Mesa! As soon as you can!
This doesn't look too good. I understand this a very early screenshot. There are no articles on the page, so I really can't make anything out of this. I'm sure you can do better than this. One Love.
