Project DDT is a game engine to run the classic Diablo game and its Hellfire expansion on modern computers.
The whole thing is in early alpha. No game-play and only Linux is supported.
I haven't used it but I'd like to see a Windows exe file plus third party resources support. Update April 26, 2013. I have dual booted with linux to try this out. While it works, there are still a whole lot of bugs on it. I am not skilled enough to iron those bugs out. You can load hellfire.mpq and diabdat.mpq and there's a spot for alternative MPQ files but I couldn't get The Hell or Awake to work. I don't know what would happen if it did.. There is source.zip with all the pertaining files. I do not know how to cross compile to Window, if someone has a way of doing this, please let me know. As for the content, it is clear the control one would have over the game mechanics. He did set up a rather familiar Tristram setting but it isn't pretty. I couldn't get a dungeon to work and forget about monsters, equipment and quests. This is clearly an alpha build. I see huge potential in this and for that, I rated as a recommend, hoping it would grab some attention and we can try to build a game upon this engine. Updated May 2, 2013: I've written a review of this project on my blog: khanduras.net/2013/05/abandoned-projectddt/
