Doom 2 (GZDoom) Introductory Modding Guide

A simple overview of Doom 2 modding with GZDoom. I can't thinkg of a reason why anyone would want to mod the base Doom 2 instead of GZDoom. It has a lot of features and can be a bit complicated, hopefully this is easy enough to follow.

In this video we'll be overwriting some existing files and changing stats on a weapon. Creation isn't much difference than overriding in DECORATE, but I'd like to save that for an advanced video. I also don't cover 3D models. While impressive, there are plenty of better 3D engines to play with. This is a great engine for sprites.

There is no sound... apart from when talking about sounds in to the mod. So brace yourself for some chainsaw madness.

You may jump sections in the video, but it was designed for a complete viewing if you're completely new to modding. A lot of the information is available on the wiki and forums, however when people start talking about DECORATE (I didn't shout that) without explaining what it is... you get a bit frustrated and make a YouTube video.

Though this is for DOOM 2, a lot will apply to every other title which GZDoom supports.
