To clarify for all of you.
Some time ago me, Dopefiend, Sleepmaster and NolaFTW decided to start a 4-way collab. We were going to create the "unofficial" 5th DLC for this game. "Project Sanctuary / The Fall of New Haven" and "Project The Dust Wastes" were once the premises of this DLC. However due to communicational problems and such NolaFTW and Dopefiend left this collab and went their separate ways. Meaning that "Project Sanctuary / The Fall of New Haven" (Dope's' original DLC) was split from my original "Project The Dust Wastes" DLC.
What Dopefiend has planned when it comes to this project of his is unclear to me. All I know is that he's busy with his Hyperion Apex Facility, jumping puzzles DLC.
However me and Sleepmaster decided to continue the "unofficial" 5th DLC joint venture. The 5th DLC will now contain my "The Dust Wastes" project and in the future custom maps built by Sleepmaster himself. Starting next week I'll continue with uploading video's for my YT channel (I've got a special LP series going on: https://www.youtube.com/playlist?list=PLCIUJFHE-NAX3et0l_YLNlHGNevQnr5yQ) With the next few episodes containing a very serious discussion about me and Sleep's' 5th DLC program.
