Doom 3: Resurrection of Evil is a horror first-person shooter video game developed by Nerve Software and published by Activision. It was released for Microsoft Windows on April 3, 2005, as an expansion pack and sequel to Doom 3 and on October 5, 2005, for the Xbox video game console. The Xbox version does not require the original Doom 3 in order to play, and includes The Ultimate Doom, Doom II: Hell on Earth and Master Levels for Doom II. The video game features eight multiplayer game modes. Resurrection of Evil features twelve new single-player levels, six new enemies including the hunter, four new multiplayer maps as well as new weapons such as the double-barreled shotgun originating from Doom II. Gameplay Resurrection of Evil adds in two new main features to the gameplay that the player can use throughout the game. The first, is a tool that was originally developed for Doom 3; "the Grabber".

It also allows the player to catch fireballs and throw them back at the enemy. Resurrection of Evil has come under some criticism about the use of the Grabber due to the prior popularity of the similar weapon in Half-Life 2. The developers have commented that the tool was originally in Doom 3 before Half-Life 2, and was used to create "damaged" rooms; instead of building a ruined room, they would build a pristine room and use the grabber to "damage" it realistically. There are three major differences between the Grabber and the Gravity Gun. The first is that the Grabber has a limited charge, and thus can only hold onto an object for several seconds. The second is that the Grabber creates a distortion effect that can obscure the player's vision when in use. The third, and by far most important in terms of its impact on gameplay, is that the Grabber can catch and throw projectiles and small creatures, whereas the Gravity gun cannot. This makes it the best weapon for defeating several types of monsters, including the Lost Soul, Cherub, and Trite, which it can throw and kill outright, and the Imp, Cacodemon, Hell Knight, and Vulgar, whose projectiles it can catch and throw back. It cannot catch Revenant missiles. The second additional feature is the
