Indie games

Indie games are games developed by small teams. For an overview of indie games in general, one may refer to the ; this article is specifically for indie games created with the Doom engine or one of its source ports.

An indie game is a special case of a total conversion. While a total conversion is still meant to be loaded as a mod, and therefore requires the base game data, an indie game is fully standalone and does not require ownership of any other game to be played.

Some indie games utilize (and include) the Freedoom IWAD as a bootstrap for custom content or include a fake IWAD that contain the minimum amount of lumps required to launch a game.

Vanilla
Relatively few indie games target the vanilla Doom engine, since it does not have any provision to support custom IWADs and offer very little ways of customizing the game behavior. The use of DeHackEd offers more possibilities but since distributing a modified copy of the original executable is technically copyright infringement, a standalone game will still have to be distributed with a source port, or only be distributed as game data and leave obtaining the executable to the end user.
