A work-in-progress free and open-source replacement for the Diablo I engine. Simply import the Diablo assets, and enjoy the same old game with faster performance and modern resolutions, and first class support for mods.

What's this all about?

We love Blizzard's popular game, Diablo. We love it so much, in fact, that we're willing to spend our precious time developing a free and open source solution for those wanting to play it on a modern computer.


Is that legal?!

Short answer, yes. We don't distribute any copyrighted game assets, which means you'll need to have a copy of Diablo to be able to play.

  • Pathfinding!

    November 27, 2016 by wheybags

    Thanks to konopka90 and pengyz, we now have pathfinding in freeablo!


  • More multiplayer progress

    October 15, 2016 by wheybags

    You can now hit things until they fall over, even in multiplayer!

    Also, the multiplayer code has been massively overhauled, so things are in a much better state for moving forward.

    Anyway, here’s a quick video of some things being hit until they fall over:


  • Multiplayer progress + Tchernobog

    July 17, 2016 by wheybags

    Hi all,

    There’s been some progress on multiplayer, I’ve been working to switch to a unit tested serialisation framework based on the gafferongames article series here.

    So far most stuff is working, with the notable exception of monsters in the dungeon. Below is a short video demo:


    Also, another big announcement, following this forum post, brightlord, the developer behind the Diablo 1 HD mod/Tchernobog has shared the sources for Tchernobog with me to use as a resource for the further development of freeablo. So, a big thanks to him for that, and here’s hoping it’ll come in useful in the future. I’m afraid, however, I can’t share the sources at the moment, but chunks of them will probably end up in the freeablo codebase.

  • Update + forums fixed

    March 20, 2016 by wheybags

    Hey, so not much has been happening in the past month or so because work was pretty hectic for me and I had no free time to work on freeablo.
    The good news is that has changed. MP is pretty close to done, expect a proper video of that soon.
    Also, the forums were absolutely inundated with spam, that’s been fixed now, and hopefully won’t happen again, as I’ve enabled captchas for signup.

  • Multiplayer!

    August 30, 2015 by wheybags

    mp gif

    Probably the only feature half of you even care about :p
    Anyway, perhaps an overstatement, as what you see is just the player being synced, but I’ve started on implementing mp, so you should be hearing more about it “Soon”

  • v0.3 released

    August 5, 2015 by wheybags

    As it says, v0.3 finally released.

    Big features this time round are level 3 level generation, and some cool new gui stuff from konopka90 and Exairnous.

    Im hoping that for v0.4 I can get a start on combat and multiplayer, so it should be a more exciting one (a lot of the stuff in this release is a bit “invisible” to end users).  I’m also gonna try actually write something on here a bit more often, keep it updated with project status and the occasional general interesting gamedev bit I run into.

    Anyway, (slightly less) crappy video, and changelog below:


    - Bugfix - monsters spawn on level stairs #112
    - Threading refactor #107
    - Hotkey selection GUI #106
    - level 3 dungeon generation #103
    - UI chroma key transparency #96

  • Media section

    November 14, 2014 by wheybags

    Another short update – I made a media section with some screenshots + a basic video: http://freeablo.org/?page_id=39

    BTW: If any of you out there are good at web (or just ordinary) design, it would be nice to get custom wordpress + phpbb themes (that match), and/or a freeablo logo.

  • Quick progress report

    November 13, 2014 by wheybags

    So, it was called to my attention that I haven’t updated this site in a good while.
    Since the last update, there’s been a few changes – the big ones being gui and level generation for dungeon levels 5-8 (still in a pr, https://github.com/wheybags/freeablo/pull/93)
    Dungeon level 5:

    Main menu:

    Screenshot from 2014-11-13 15:16:43

    Pause menu:

    Screenshot from 2014-11-13 15:16:52

    Char and Inv windows (don’t actually do anything yet):

    Screenshot from 2014-11-13 15:21:39


    As you can probably see, the gui bits are fairly placeholder for now, missing some visual features (like trasparency for that ugly green, and animation for the spinning pentagrams and fire), but they are a good base in my humble opinion 😛


    Anyway, development does continue, in fact we’re probably approaching a point where we can release v0.2, if you take a look at the github milestone: https://github.com/wheybags/freeablo/milestones/v0.2, it’s mostly finished, with music being the only big feature remaining.
