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.
Wow, I've been working on the beginning of this mod for a while.
This is to show why I've restarted so many times - every iteration gets better and better as I learn more about hammer, and this is to show the 'final' version compared to a previous 'improved' version.
