SANTA MONICA, Calif., Oct. 25 /PRNewswire-FirstCall/ — id Software(TM) and Activision, Inc. (Nasdaq: ATVI – News) will unleash an all-new assault on humanity with DOOM 3: Resurrection of Evil(TM), the official expansion pack to the fastest selling PC first- person action game ever in the U.S., according to NPD Techworld. Co-developed by Nerve Software and id Software, DOOM 3: Resurrection of Evil continues the terrifying and intense action of the already classic DOOM 3, which Maxim and Computer Gaming World awarded “five out of five stars” and the Associated Press called “one of the scariest games ever made.” Through the discovery of a timeless and evil artifact you now hold the powers of Hell in your hands, and the demons have come to hunt you down and take it back. Following the events of DOOM 3 and featuring new locations, characters and weapons, including the return of the double-barreled shotgun, DOOM 3: Resurrection of Evil expands the terrifying action that fans and critics have been raving about. The title will require the full retail version of DOOM 3, and has not yet been rated by the ESRB. “DOOM 3 defines first-person cinematic action, and the expansion pack continues right where we left off — with a terrifying atmosphere, a new story and one of the most classic weapons ever, the double-barreled shotgun,” states Todd Hollenshead, CEO, id Software. “Now that fans have survived the horrors and edge of your seat action of the original, DOOM 3: Resurrection of Evil delivers players deeper into the heart of the UAC to uncover new secrets and technology used to destroy the demon force that’s Hell-bent on destroying you.” Building on the most advanced game engine ever created, DOOM 3: Resurrection of Evil continues the frightening and gripping single player experience of the blockbuster original.

What games that pit the player against the ravenous undead hordes do you enjoy? Here are a few off the top of my head:
- DOOM! From the very first area of E1M1, you’re trading fire with armed zombies.
- Doom 3 – Along with the expansion pack, Resurrection of Evil, the early portions of the game feature former human enemies rather prominently.
- Quake 4 – Has a zombie survival level in the main campaign; there’s also this user-made level, Zombietown. There were also zombies among the rogue’s gallery in the game’s predecessor, Quake.
- Killing Floor – a total conversion for Unreal Tournament 2004 that has a cooperative multiplayer mode.
- Boxhead: The Zombie Wars – an above-par Flash game with gameplay similar to Robotron.
Edit: Thanks to the readers who pointed out these titles I missed.
- Majesty – one of the early Linux Game Publishing titles, zombies are among the creatures in the strategy game’s kingdom.
- Return to Castle Wolfenstein had rotting Saxon warriors hunting the player through catacombs.
- Neverwinter Nights’ original campaign had a zombie-infested village.
- Black Shades portrays a psychic bodyguard who must deal with zombie assassins.
- Eternal Damnation – a total conversion for Postal² (also included in the Postal Fudge Pack), because “how many mods let you punch zombies in the face with knuckle dusters?” including an actual plot.
- Penumbra: Overture includes zombie dogs.
- Myth II includes undead units, how could we forget?
