Doom 3 alpha version

Doom 3 alpha
The Doom 3 alpha version was the first version before the final game. It has many differences between the final game and this version. The motives because it wasnt released is because a Hacker leaked the Alpha version and distributed it on internet. Since them the final version was reformed.
