Five gameplay elements Doom invented that nobody stole

Game-changing exploits

Why aren't bugs fun anymore? Nowadays, the only time you hear about a glitch is when a game keeps freezing, or somebody's mouth doesn't move properly in a cutscene, or it’s an online multiplayer goof that actually ruins the experience for everyone else. When Doom was around, glitches weren't just about throwing your keyboard out of the window in frustration. They were both fun and bizarrely amazing.

Above: Whoops

For instance, there is a rare glitch in which a monster will commit suicide if it throws a projectile at an exploding barrel and gets hit by the splash damage. Since the monster technically caused damage to its own HP and is programmed to infight with anything that does so, the monster targets itself and will commit seppuku before your eyes. Then there's the famous "telefrag" glitch, where you can use a teleport at the same time as an enemy and cause them to explode. All good fun!

There are bags full of astounding exploits in the Doom games, many of which are very rare and take dedicated skill to recreate. You just don't get that in games anymore. It's all corrupted save files or bricked consoles ... and they are, unfortunately, not rare at all.

Chex-themed modifications

Chex Quest was a total conversion of The Ultimate Doom, with redrawn sprites that turned a Hell-drenched game full of slavering demons into a charming adventure in which a man wearing cereal for armor shot non-lethal transportation guns at cute green aliens. So popular was this game (the first ever CD-based title to be packaged into cereal), that sales of Chex increased by 200%. It didn’t stop with Chex, either. There are countless total conversions that redress Doom in infinite ways, each one essentially creating a brand new experience.

Above: Notice the aforementioned badass music is still in place

Why on Earth has Halo not found its way into a box of Cap'n Crunch, and where is our Killzone Krispies? Truly, Doom was such a trailblazer that nobody has ever dared walk the path it forged. Well, we will recognize all you tried to do for the industry, even if your so-called descendents have failed.

Praise be to Doom.

    I'm pretty sure Halo had awesome music & infighting. And whenever I saw a Big Daddy in BioShock I was like "aww... sh*t". But yeah, no games have blended all the elements together like Doom. Nice list :) PS Why do no modern FPS games feature fast-paced, twenty-minute levels like Goldeneye & Perfect Dark?

    Minecraft has infighting- get a skeleton to shoot another enemy and they'll duke it out... Killing Floor has some of the most terrifying non-boss enemies I've ever experienced I'll give you the other 3, but they aren't really things I look for

    Painkiller had some kickass music.

    can anyone tell me where to download doom for free? or quake
  • highhardroad - May 17, 2010 5:05 p.m.

    I actually found an iPhone game that has some pretty interesting infighting. Something I haven't found in other IAnything games. I bought it after reading about it in their website's forums. It's website is

    Sorry, ingame fighting was done in Blood.-
  • theschwartzb - May 9, 2010 5:42 a.m.

    Definitely infighting and several terrifying monsters in Fallout 3. I quite frequently come upon fights between one faction and feral ghouls, such as super mutants v feral ghouls or raiders v feral ghouls. Also feral ghoul reavers, deathclaws, and super mutant behemoths are all very fast hit incredibly hard and are recurring (the super mutant behemoths to a lesser extent, although they do show up several times in the game, just not as much as the reavers and the death claws.) In fact, there is a town called 'Old Olney' that is full of nothing but deathclaws.
  • MyGameName - May 8, 2010 2:16 a.m.

    @Vitoruss1 Halo note is incorrect as those were all separate factions. All enemies in Doom never showed any notice of each other unless hit by a stray bullet. GTA note is incorrect. They're not talking about CHEAT CODES. They are referring to the final game as is, without console commands, special button inputs, or other commands that force the game to behave in a certain way.

    I'm only so so on shooters in general, the all action ones get dull really fast to me. That said I worship doom, and constantly try to find a PC version of it that will run since mine has litterally decayed until it lost data. All hail your DOOM...
  • LIKEUCARE - May 7, 2010 9:40 p.m.

    Holy crap... and I forgot one hell of a scary FPS monster... In STALKER: Shadows of Chernobyl... the mutant with the telekinesis attack made me jump for sure! The Bloodsuckers too first time I met 'em... I can't comment to STALKER Clearskies and Pripyat since I haven't played 'em yet... I would imagine they'd have new scary monsters as well! Oh and a friend of mine told me that in Metro 2033, theres many scary mutants in that too, although, he's easily scared of anything so not so sure about that fact... Heck, it took him about 2 years to play DOOM 3... once he got through, he could finally play scary games hah...
  • LIKEUCARE - May 7, 2010 9:32 p.m.

    I gotta agree with todays videogames, the soundtrack lacks rock/metal/techno tunes. It's all ambient and atmosphere, while nothing's wrong with that, but I would truly crave for a pure return of an old school FPS game. Kinda like the good old DOOM/Quake style! As for scary monsters, I could think of many... For instance, in DOOM 1, think the Baron was the scariest for me... his scream and howls made me run like hell backwards lol! In Quake 1 "Huge White Guy" were scary as hell first I met 'em! Quake 2... wasn't much scary, but it was all about pure action with a rock-solid soundtrack. Quake 3... very good action, soundtrack was good, but slightly below Q2. As for Q4, I think many agrees that its a forgettable game, sadly. FPS scary monsters... well, in FEAR, those assassins made me jump first time... oh and those nightmares specters too. Condemned enemies were something too, jumping at you at any moments. The grisly bear in Condemned 2... man that was scary! The T-Rex from the latest Turok game... whew he chumped on me many times till I finally beat him! Serious Sam First Encounter's bosses were a fearsome sights! Return to Castle Wolfenstein... MANY SCARY MONSTERS! The 2-arm walking "mechanoid" was scary... as were the zombies, shooting you souls at you. The Rumbler from System Shock 2 was scary as hell! In Half Life 1, those cloaked female assassins... Think in Unreal 2 The Awakening had some scary monsters too... Clive Barker's Undying... many scary monsters there as well. Thief 1 zombies, ghosts and apparitions were scary stuff! AVP 1999 marine missions were scary stuff... first time you saw the aliens for the first time scared the shit out of me. Even when you first meet a predator, he was scary too... kept aiming at you from a long distance with his PlasmaCaster and could kill you in one shot. The Alien Queen on the last mission was freaking scary! You could only kill her Ripley style, hence, everything you'd do to her only slowed/stunned her temporally. Ah, good moments! AVP2 cartoonish look spoiled the fear factor IMO, even if the game itself was a tad greater than AVP1. As for AVP 2010, even if I disliked it a lot in all imaginable ways compared to previous AVP games, it has its moments... the Praetorian boss fight in nightmare mode was fearsome! As for more scary monsters, guess they'd be in Third Person Shooters style... from the games like Dead Space, Resident Evil series, Silent Hills series, The Suffering series, The Chronicles of Riddick "sewer lurking mutants"... Last point... many disliked DOOM 3, but I still think it was a pretty good single player game overall. Surely, it missed a few elements here and there, skipped the rock/metal music... but it does have its moments for sure! Oh and, anyone here feels the same that the DOOM 1 Baron was scarier than DOOM 3 Hellknight?

    Exploits aren't bugs. And telefragging was part of the game. As infighting isn't as rare as you guys seem to claim. Lots of RPG's have it, like the wonderful-but-very-buggy Gothic games.
  • MaynardJ - May 7, 2010 11:26 a.m.

    Archvile, the Cyberdemon, Revenants, the Cacodemons and the Spider Mastermind are still some of the most terrifying parts of my teenage gaming years. Jesus Christ, those guys were scary. Last time I played Doom must have been about 2 years ago. I turned off the music and played Metallica and Bad Religion CDs as a score. How many other FPS games make that possible, with all those cutscenes these days? Another FPS I'd like to see "copied" a lot more: No One Lives Forever, especially part 2. Probably the last FPS I played, so I'm not really up to date on the genre. But if any of you people can tell me about another FPS that is as much fun as NOLF2 I'll buy it.
  • TheEvilSideofEveryone - May 7, 2010 5:34 a.m.

    MW2 had infighting on one LvL so it just took some one a long time to rip that off.
  • Spybreak8 - May 7, 2010 4:39 a.m.

    Archvile burned you which made you fly into the air. That was the main thing that freaked me out. I was just playing Borderlands and it's fun to get the bandits to fight skags!
  • keithburgun - May 7, 2010 4:05 a.m.

    I just wanted to let you know that my new iPhone game has in-fighting. And it's because I love DooM so much.
  • hardcore_gamer1990 - May 6, 2010 11:30 p.m.

    Assassin's Creed has certain exploits that will change the way you play... Try searching The HyperBlend exploit on YouTube?
  • TURbo - May 6, 2010 11:08 p.m.

    Doom was the first game to use the Doom engine. Heretic was afterwards.
  • JimSterling - May 6, 2010 11 p.m.

    Metal Gear Solid isn't an FPS, while the infighting is fully scripted and designed. "Monster infighting" is a particular type of infighting that's scripted to trigger due to friendly fire. Not a lot of games copied that. As far as scary enemies go, it's mostly opinion, but again, this is about FPS games, not Zelda and the like. Nevertheless, it's more opinion than anything else, and I've seen a lot of people get angry over it, which strikes me as silly.
