Description
[λ]Black Mesa is a corp. with our headquarters in New Mexico and is used to privately research Technology and other stuff. Guild Book: http://forum.roblox.com/Forum/ShowPost.aspx?PostID=182523138 The various Black Mesa facilities are loosely grouped into seven Sectors, as well as various Areas and Levels, all linked together by the Black Mesa Transit System or Sector E Materials Transport. Each sector has a letter ranging from A to G, and bears the name of its main facility. Thus Sector E Bio-dome Complex does not have only alien study labs, and Sector D Administration does not have only administrative offices.
