In the first episode, you wake up inside a repurposed apartment in Mars City. You do not recall how you got there or any specifics about your person. You soon meet Samantha Miles, an agent of a sketchy world-wide conglomerate, who claims to know you. While she helps you with your identity, you aide her in the quest to find a long lost friend and missing agent. When the original events of Doom 3 unfold, the two of you must scramble for safety while still tracking down the missing agent and your identity.

Prerequisites

Latest version of Doom 3 and latest version of Doom 3: Resurrection of Evil. Doom 3: Phobos does not work with Doom 3: BFG Edition or any NON-Windows version of Doom 3 and Doom 3: Resurrection of Evil.

Installation

Unpak the folder named ‘tfphobos’ into the root of your Doom 3 installation folder.

You can not start Doom 3: Phobos through the Doom 3 or Doom 3: Resurrection of Evil mod list in the menu.

You need to create a shortcut with ‘Target’ Eg: "[Doom3Dir]\DOOM3.exe" +set fs_game tfphobos +set fs_game_base d3xp.

Or place the Phobos.bat file in the root folder of Doom 3 and run that.

If you own Doom 3 and Doom 3: Resurrection of Evil, through steam you can also set +set fs_game tfphobos +set fs_game_base d3xp under the Doom 3 properties via the Steam client.

We do not guarantee the original campaign or multiplayer in Doom 3 or Doom 3: Resurrection of Evil to work with Doom 3: Phobos. Neither do we guarantee any additional mods you install on your own, will work with Doom 3: Phobos.

If you experience any problems, please try and have Doom 3: Phobos installed on a fresh copy of Doom 3 and Doom 3: Resurrection of Evil, with no other mods installed.

There is no CD-KEY window in Doom 3: Phobos. If you are playing Doom 3: Phobos with a fresh install of Doom 3 you need to start up Doom 3 without Doom 3: Phobos, and insert your CD-KEY.

For AMD users experiencing any problems (Thanks to Stradex and Anton for telling us):

1. Create a copy of doom3.exe called phobos.exe

2. Edit the .bat file to use Phobos.exe

3. Ingame menu disable HDR and bloom if the mod uses it
