First method is to purchase the game from, for instance, the idSoftware store, Steam, or Amazon.Īlternatively, one can download Freedoom which is free and legal. There currently exists two methods of obtaining the Doom or Doom 2 IWAD file. As a result, the IWAD file plays an important role with Zandronum and every other Doom based engine, and running any game without the IWAD file is impossible.įurthermore, if the user has already installed Doom from a floppy disk, or from a CD such as ' Doom for Windows 95' or ' Doom 2 for Windows 95' for example, the IWAD can be used from those installations of Doom or Doom 2. Moreover, the IWAD file contains information such as maps, sounds, music, monsters, items, and other visual and environment aspects of the game. An IWAD or Internal WAD file is necessary in order to play Doom, Doom 2, ZDoom, GZDoom, Zandronum and any other Doom based engine available. When Zandronum is loaded for the first time within the Windows® platform it may ask the user to specify a directory that contains either one of or more than one of the listed IWAD file(s). Zandronum's welcome IWAD search window-box will appear when an IWAD is not found within the parent directory.
