The M.A.R.T.I. Initiative is a mod for Portal 2 taking place in alternate facility to Aperture Labs during the 1980's, following their attempt to create an AI by the name of M.A.R.T.I.
The first map was completely remade by H.Grunt.
He got rid of all the somewhat uneeded open spaces
Now this looks much more better, I like those factory concrete walls more than old observation ones. Good job !
Tell H. Grunt good job x3
