The new Doom comes with a copy of the original.


The source code for the original Doom and Doom 95 first-person shooter video game was released into the public domain in 1997. Since this release, there have been dozens of source ports and clones. This includes clones of the original Windows version of the game Doom 95 and the MS-DOS versions as well. 

Sources and Clones

Many of these clones have come and gone but a few survive and are still updated to this day. In fact, one of the Doom source ports called PrBoom was used as a template by id Software in the development of the iOS version of Doom. These clones and ports have also fixed bugs and enhanced certain gameplay aspects and graphics along the way.

Doom has also been ported to at least 20 different video game platforms and computer operating systems. One of the latest ports includes the 2013 release of Doom for the retro Commodore VIC-20 home computer system.

One thing that has remained constant through all of these Doom and Doom 95 source ports is the groundbreaking gameplay that Doom introduced and what has made it one of the most influential and classic PC games of all time. The vast majority of the source ports and clones also stay true to the original by recreating the same the nostalgic early 1990s VGA computer graphics.

Finding the Games

In addition to PrBoom, other Doom source ports include GZDoomZDoom, and Zdaemon. Zdaemon is unique as it brings a multiplayer component to Doom. It allows players to connect to multiplayer servers and play against online opponents in various game modes. It faithfully recreates all aspects of the original Doom but brings it into the world of multiplayer shooters.

AllGamesAtoZ, which hosts some of the download files, also contains additional information on some of the more popular Doom Source Ports.

Depending on which version is downloaded, DOSBOX may be required to run old DOS games on a PC running a current version of the Windows, Mac OS X or Linux operating systems.
