Diablo II reimplementations (Riiablo, D2MOO)

This site is not affiliated with Riiablo, The Phrozen Keep or Blizzard Entertainment. We do not host any files and only link the projects’ official repositories.

What it is

Diablo II (2000) and its expansion Lord of Destruction (2001) are still played, and Blizzard remade them as Diablo II Resurrected in 2021. Unlike the first Diablo, which has the complete fan source port DevilutionX and a browser version, Diablo II has no finished open-source engine. Two projects come closest.

Riiablo

Riiablo is Collin Smith’s “attempt at rebuilding Diablo II from scratch” in Java with LibGDX. The README admits “there is still a long way to go, but a lot of the core is there”. It uses 100% original Diablo II assets, which you must already own, and aims to stay faithful while adding conveniences such as auto gold pickup. It supports wide aspect ratios (4:3 to 21:9) at the original 480-pixel height and runs on Android as well as desktop.

The last release, 0.0.4, dates from 28 May 2021, and the repository was last updated in January 2025.

D2MOO

D2MOO (Diablo II Method and Ordinal Overhaul) is “a re-implementation of the Diablo2 game coupled with patching facilities for modders”. It replaces parts of the original game’s code with readable reimplementations while running the original. It deliberately does not fix bugs yet, to stay close to the original, and requires the original game’s assets and binaries. It is built with Visual C++ and CMake and is updated constantly (last update 2 November 2026).

What you need

• Your own original Diablo II (and Lord of Destruction), installed. Riiablo reads its assets; D2MOO also needs its executable code.
• For Riiablo: Java on Windows, Mac or Linux, or an Android device, and patience with an unfinished game.
• For D2MOO: Visual C++ and CMake on Windows to build it.

We do not link any copies of the game.

Is either worth using?

For modders, D2MOO is an active and serious tool. For players, neither project replaces the game yet. D2-Web is a newer, separate project that already plays in a desktop browser with your own game files, and part of it is adapted from D2MOO. Diablo II Resurrected (official) or the original Diablo II with Blizzard’s patches are the practical ways to play. For the first Diablo, DevilutionX and the Diablo browser port are complete.
