Diablo 1 HD MOD is currently the most advanced and popular Diablo 1's HD mod package, made by Wojtek25. It includes two modification projects with code names: Belzebub (single-player) and Tchernobog (multi-player).

The original Diablo does not support high-resolution display. Belzebub version completely solved this problem. It supports multiple resolution settings (up to 1920 x 1080), and allows to switch between window & full screen modes. This makes the view of game map become much broader, and makes the overall graphics become more clear.

Tchernobog is actually the multi-player mode of Diablo 1 HD MOD: Belzebub. This MOD new added LAN and Internet online game modes. Of course, it also retained the offline game mode. In game, the character player uses will be shared in both single-player and multi-player modes, which makes the entire game look brand-new.

You must know something about this: Diablo 1 HD MOD not just simply ported Diablo 1 onto a new generation of Windows system; At the same time, many wonderful contents from Diablo 2 and Diablo 3 were added into it, even the enemies were endowed with new skills!
