In August 1996, Blizzard was hard at work developing Diablo. For promotional purposes, they produced a build to be distributed as shareware called the Pre-Release Demo. Blizzard intended this build to be locked down: players would be restricted to the Warrior class and the first level of the cathedral.

It is well known that these restrictions are easy to bypass. Doing so gives access to a snapshot of the entire game as it existed four months before launch.

However, there are two problems playing with the limitations removed:

  1. Many graphics are missing from the MPQ ranging from player animations to monster animations and entire level tilesets.
  2. Crashes abound at every turn.

This mod aims to tackle both these issues while maintaining the spirit of the PR Demo. If it ain't broke then we won't fix it. If something stops the player from getting to level 16 then we will analyze and address.

Bugs are expected since, in August 1996, the game was actively under development. These bugs are left in to be faithful to the state of the game as it was being developed.

Hello ModDB!


Howdy folks,

This mod of the Diablo Pre-Release Demo has been a few months in the works already. Most of the development happens on our GitLab and discussion on Discord. However, to reach a wider audience and provide wider availability, I thought it only makes sense to submit it to the best darn mod site out there.

I'm looking forward to the new opportunities that this opens up for this mod!
