Doom v0.2

Doom 0.2 was the first publicly released alpha of Doom. It was released in February of 1993, and only two months of work had been done on the game at that point.

The "technology preview" includes only one small level with no changes in elevation, no doors, and no items. Only three enemies are present—the imp, the demon, and the Baron of Hell—and their sprites and programming consist only of walking in place.

The only weapon, an early version of the shotgun, has no effect on the monsters. The texturing is scant, though many textures and flats present eventually ended up in the final game. Floor, ceiling, and wall textures can be cycled individually by pressing the number keys 0-9.

The heads-up display/status bar in this alpha is larger and more complex than those that followed. An automap, item list, and weapon stats are among the extra elements visible.
