Doom 3 Alpha - Full Gameplay

This is a full demonstration of the introduction sequence and three levels available in the Doom 3 alpha that was leaked in 2002 shortly after its display at that year#039;s E3 event. This is a "proper" playthrough of the levels that includes and triggers all of the scripted sequences and events as they were intended to be. Hence, everything you see me do in this video is more-or-less a direct recreation of the game#039;s presentation at E3 2002, although I chose not to use god mode.
