OpenDiablo2

An open source re-implementation of Diablo 2 in C#

About this project

This is an attempt to re-create Diablo 2's game engine in C#, and potentially make it cross platform as well. This project does not ship with the assets or content required to work. You must have a legally purchased copy of Diablo 2 and its expansion Lord of Destruction installed on your computer in order to run this engine. If you have an original copy of the disks, those files should work fine as well.

Please note that this game is neither developed by, nor endorsed by Blizzard or its parent company Activision.

This game is a clean-room implementation based on observations of how the original game works. Aside from the data file formats themselves, we have not and will not reverse engineer the original binaries of the game in an attempt to copy or duplicate intellectual property.

Diablo 2 and its content is ©2000 Blizzard Entertainment, Inc. All rights reserved. Diablo and Blizzard Entertainment are trademarks or registered trademarks of Blizzard Entertainment, Inc. in the U.S. and/or other countries.

Building

To build this engine, you simply need to have Microsoft Visual Studio 2017 installed with C#/Windows support. Although we currently do not support building in Linux with MonoDevelop, we would like to begin adding support for Linux and Mac in the very near future.

Running

When running via VisualStudio, go to the debug tab and specify the following command line options:

-p "C:\Program Files (x86)\Diablo II"

Substitute the path with wherever you have installed Diablo 2 and its expansions.
