Doom 3 alpha version

History
A work-in-progress version of Doom 3, called the "E3 Demo Alpha" (also known as the "Alpha version"), was placed onto the Internet in late 2002. As with most video games, this work-in-progress version differentiated from the retail version in several aspects. These differences include, but are not limited to, the following:


 * Graphics for the Heads-Up Display (HUD)


 * Models for the weapons & enemies


 * Sound effects for the atmosphere, enemies & weapons

The doom 3 final was supposed to look like the alpha if the e3 demo wasnt leaked. some of the weapons expect those that were shown. were based on quake 3 models with then were turn into high resulution models. the three levels were based on some early designs of the final version.

= Levels = e3_1 is based on an early concept of the recycling plant mostly the atmospere. Were the Marine discovers the consequenses of delta labs experiment gone wrong.

e3_2 is based on a mix between the EnPro and CPU complex and the player must get past the commandos and replace the extraction canister.



e3_3 is a very early content of the alpha labs with influenses of sector 1 and 3 it ends with the hellknight eating the marines head. if the game got complete the hellknight was to be some kind of mini-boss if defeated the player would exit the alpha labs.







e3_intro is the intro movie with is really a map but shows both early Mars city and Delta labs.
