One of the most revolutionary things about the original DOOM was its customizability. Built from the ground-up to be easily modified, DOOM (1993) and DOOM II may not have created the PC modding scene, but they sure kicked it into high gear, and to this day, DOOM is one of the most frequently and passionately modded games. Looking to dip your toe into that vast ocean? Here’s something you’ll need to get started.
3: A Map Builder
Once you have the ability to run DOOM (1993) or DOOM II on your modern computer, it’s time to start getting down to the nuts and bolts of building your own DOOM mod. It’s time to start creating your own levels!
Over the years, many map editors have come and gone from the DOOM modding scene, but today it’s hard to beat Doom Builder and its offspring, GZDoom Builder. Doom Builder proper is a powerful, yet user-friendly, application that allows even newcomers to quickly get up to speed on map design. Tools like an easy-to-understand interface and a robust map-analysis feature make the process as close to foolproof as possible.
For those in search of a more powerful level-building tool, there’s GZDoom Builder. This version is specifically designed for creating maps that use the fancy new features introduced in modern engines like ZDoom, such as custom objects and new means of locomotion.
Whichever you choose, be warned: Map design is where dabbling in modding can turn into an obsession.
