An IWAD - short for Internal WAD - is the main resource file for a Doom-engine game, containing all the game's original sounds, levels, and graphics. EDGE needs an IWAD file in order to play; without one the EDGE engine has no game data to use.

Supported IWADs

Notes:

  • Some file names are links to a page on the

where you will find checksums for known versions of the concerned file.
  • Some files have conflicting names; EDGE provides you with possible aliases. Note that an IWAD is actually identified by its content rather than its name. Also, any archive format supported by EDGE can technically be an IWAD.

In addition to them, some "total conversion"-type mods can be played as their own IWAD; however since they are not detected as such by EDGE, you need to use the -iwad command line parameter.

In order to play a custom level designed for any of the above games you have to have that particular game's full IWAD (loading PWAD with shareware, demo or teaser versions is disabled). If you do not have the necessary IWAD, or if you have an old, unpatched version of the IWAD in question, you might experience undefined behavior. (But often old versions are accepted too.)

The IWAD file(s) should be placed in a directory where EDGE will find them. This includes the same directory as the EDGE executable, as well as those pointed to by the DOOMWADDIR environment variable. On Linux, the directories $HOME/.EDGE and /usr/local/share are checked by default.

Obtaining IWADs

As noted above, some IWADs can be downloaded freely; however most "full" games are not and must be bought from one of the following sources:

GOG.com
This store offers downloadable versions of Ultimate Doom, Doom II: Hell on Earth (bundled with Final Doom and the Master Levels for Doom II), and Strife. The Final Doom version offered is the later Anthology version, which fixes many mapping errors (such as the infamous missing key in TNT MAP31).
Steam
This store offers downloadable versions of Ultimate Doom, Doom II: Hell on Earth, Final Doom, Heretic: Shadow of the Serpent Riders, Hexen: Beyond Heretic, Hexen: Deathkings of the Dark Citadel, and Strife; as well as the Master Levels for Doom II which is a set of PWAD, not an IWAD.
Warning: following the release of DoomWikiLogoIcon.pngDoom 3: BFG Edition, the Master Levels are no longer available to purchase individually but can be bought as part of the Doom Classic Complete Pack.
Note: The version of Hexen: Death Kings available on Steam is not patched. You need to download and apply the Death Kings 1.1 patch first. (The "readme.txt" file it tries to patch has been renamed readme-dk.txt by Steam, but is not important.) All other IWADs from Steam are fully patched.
Amazon.com, eBay.com, etc.
Second-hand copies of the original games can be found on such sites.
Flea markets, used-games bins in brick-and-mortar stores, etc.
It's mostly a matter of luck, but they can still sometimes be found this way.

Custom IWADs

EDGE is currently working on the ability to define any WAD/distro/archive as an IWAD or IPK (IwadPacKage) - currently this is only available by using the -iwad switch.
