The Legend of DOOM Offers a First Person Remake of the Original Legend of Zelda Game in the DOOM Engine

First, you’ll need to download the latest version of GZDoom to your computer. You’ll find it here (the blue icon). Next, you’ll need a DOOM iwad (basically, a DOOM game file). You can pick up the original DOOM on Steam or GOG, but any DOOM iwad will work here. Finally, you need to download the latest version of The Legend of DOOM mod. At the time of writing, that’s version 1.1.0, which you can find here, but double-check the official page to see if any new updates are out.

How things move from here depends on your platform. If you’re using Windows, right-click the GZDoom zip in your Downloads and extract all contents to a new folder. Do the same for the DOOM iwad and The Legend of DOOM file. If you bought DOOM via Steam or GOG, GZDoom should be able to find it automatically. Now, launch The Legend of DOOM, then tell Windows you want to use the GZDoom app.

If you’re on a Mac, it’s a tad more complicated. Open Finder, then choose “Go” from the menu bar and hit “Go to Folder.” Type ~/Library/Application Support, then hit Enter. Here, create a new folder titled gzdoom. You’ll need to move the DOOM iwad and The Legend of DOOM file You may need to enter your password to continue. Now, unzip the GZDoom zip in your Downloads. You can move it somewhere else to clean things up, but you don’t have to. Now, launch The Legend of DOOM, and, if everything is in order, GZDoom should boot right up and launch the game.
