Black Mesa Xen Achievements Guide

I discovered that some achievements are Bug, I mean they didn’t come out doing the thing that says in the description like the “Rather an Anticlimax”, “PhD in Pacifism” and “Limitless Potential”, that the truth until I finished Xen to see if the two achievements of the G-Man finals came out, but nothing.

So before someone asks me “how did I get the descriptions of hidden achievements / new achievements?”, I took it out with an external program.
