Red Doom began as a simple SP mod for Red Faction...it has now evolved into one of the biggest mods for RF. 25 years before Parker set a foot on the Red Planet, Ultor was already messing with genetics and DNA. On this particular day a small explosion causes an outbreak of a deadly disease known simply as Z-Virus. You are John Hunter, an ex-marine and now part of the SRS (Special Rescue Service). On your debut mission, to the Ultor Research Facility on Mars, you will learn what it is to survive. 13 new weapons, zombies and zombie dogs... Red Doom is here. Thanks to everyone who encouraged me to finish the mod. Enjoy! Download Red Doom
