Doom Patch description
DOOM 3 is a terrifying battle with the forces of Hell...

Science has unlocked the gates to the unknown, and now only one man stands between Hell and Earth. A sci-fi horror masterpiece, DOOM 3 is like nothing you have experienced.

Dramatic storyline, pulse-pounding action, incredible graphics, and revolutionary technology combine to draw you into the most frightening and gripping first person gaming experience ever created with one unique purpose: to scare the "hell" out of you..

Built on id's revolutionary new 3D technology, DOOM 3 is a terrifying battle with the forces of Hell. In DOOM 3, your recent assignment to the Union Aerospace Corporation's Mars research facility seemed simple enough, until their discoveries and experiments unlocked the gates to Hell itself.

Now, in an epic clash against pure evil you must fight to understand who is with you, who is against you, and what must be done to stop this nightmare from reaching earth.

NOTES FOR MOD USERS:
- It is recommended that any user modifications that have been installed to the Doom3 directory be removed before installing this update. These modifications are not supported by Activision and may not be compatible with some of the new features that are included.

NOTE FOR SINGLE PLAYER SAVED GAMES:
- Using this update will reset your progress in whatever map you are currently saved in. When loading a saved game, the player starts at the begining of that map with their inventory intact.
- Using this update will reset the Nightmare skill setting. If you are playing in Nightmare mode before applying the 1.3 update, you will need to re-enable it in the console (g_nightmare 1). After enabling it in the console, the game must be relaunched in order for nightmare mode to show up as a selectable option.

NOTE FOR WIN32 DEDICATED SERVER EXECUTABLE
- Also included in the 1.3 update is a Win32 dedicated server executable. This allows servers to be run under Win32 without a CD Check. You can launch this with command line options or configure it through the console once launched. Just launch "Doom3Ded.exe".
