Doom 0.4 was an alpha version of Doom released to testers on April 2, 1993. At this point in development, a number of elements had already been completed, and it appears that the main features of the renderer were already in place.
Version 0.4 included the following features:
- A spinning 3D title screen, which was removed before the release version of the game.
- The engine could render areas with different floor and ceiling heights, textured walls and ceilings, and different light levels.
- Collision detection was performed against the walls. However, there was no collision detection with sprites (e.g. monsters).
- Monsters appeared in some of the levels. Although they were animated, they did not move or react to the player or to other monsters. An early version of the Lost soul was included in the WAD file, although this version did not appear in the alpha.
- The player's weapon bobbed during movement and could be fired, although it had no effect on the environment or monster sprites.
- The game included a basic, but non-functional, status bar.
