Get a feel for how Diablo III plays by watching a few minutes of this playthrough of the beta: http://www.youtube.com/watch?v=FpgTFLJ_tZY

To start hacking, you need a few things:

  • Diablo III client
  • Diablo III server emulator


  1. Download, install, and run the launcher which will download about 4GB of game assets and updates. Then close the launcher.
  2. Clone the mooege repo and switch to the '8101' branch.
  3. Compile mooege with MSVS or Mono.
  4. Copy all of the Diablo III client MPQ files and folders into src/Mooege/bin/Debug/Assets/MPQ/ and run the server. Then launch the client with "-w -launch -auroraaddress".
  5. Login with username "test@" and any password.
  6. Attach your favorite debugger or run d3sandbox.

NOTE: The server emulator is in an early state right now. Many interactions do not work, monsters will not attack you and die with a single hit, some collisions are not functional, etc. It should work fine for most debugging, but do not trust the data coming from the server emulator as canonical.
