"It's gonna be like fucking Doom man - after the bombs explode. Tick, tick, tick, tick... Haa! That fucking shotgun [he kisses his gun] straight out of Doom."

"Give a man a fish, and you'll feed him for a day; teach a man to play Doom, and you'll never get another day's work out of him."

"I have no problems with the demons in the game. They're just cartoons. And, anyway, they're the bad guys."

"An old Doom map was the inspiration for 2forts, as well as TF itself"

"Over the centuries, mankind has tried many ways of combating the forces of evil...prayer, fasting, good works and so on. Up until Doom, no one seemed to have thought about the double-barrel shotgun. Eat leaden death, demon..."

"It has to be well timed. It needs to have the right components that maybe contain emerging technologies or something like, say, when Doom came out -- the Network play -- there weren't many games like that. There was a really great 3D world that a lot of people hadn't seen. It was light-years ahead of Wolfenstein. It was shareware, so it had Internet distribution. We used the Internet to get it all over the place. So it used a lot of stuff that was just becoming popular at that time. id just capitalized on it."

"Bobby Prince was a lawyer before he was a musician. He knew the legal amount of sampling that he could do without getting into trouble."

"GamesBeat: What do you say when people ask you for the quick “What’s the legacy of Doom? What’s the cultural impact of Doom?” It would make my head hurt."

"We weren’t worried about offensive stuff, because that would stop us from making what we were trying to make. As artists, we’re trying to be true to our vision. Because, in the game, you were killing demons, and demons are really a religious thing—everyone in the company was an atheist. We didn’t believe in hell or heaven or any of that stuff. Putting demons in there was just, “This is what people believe in.” We thought that the juxtaposition of future science—a space marine on a moon of Mars with all these experiments happening, it’s very scientific and futuristic—and then all of a sudden this religious thing happens, demons coming through a portal, versus aliens—"

"GamesBeat: I think Tom Hall mentioned there was a comic book that gave you guys some ideas?"

"Doom is to id Software what Revolver was to the Beatles."

"I jumped out of my seat the first time I saw one of those pink bruisers, and I cringed when I heard the imps the first time - but when I walked out into that big arena with that rocket spewing giant chasing me down I literally broke out in a cold sweat. Nothing before or since has induced that same mix of adrenaline fueled terror."

"When any device gets smart enough, someone, somewhere ports the classic first-person shooter to it, simply because they can."

"Along with Doom II, we also saw the first traces of multiplayer gaming. Playing it against your friend was something so different, and that is also why we continued to play today."

"These games are getting really realistic. Next year I might even play in the big Doom tournament. You might wonder what I'm doing here. Well, I'm getting kind of an inside look at some of these new games."

"Once you beat the big badasses and clean out the moon base you're supposed to win, aren't you? Aren't you? Where's your fat reward and ticket home? What the hell is this? It's not supposed to end this way! It stinks like rotten meat, but looks like the lost Deimos base. Looks like you’re stuck on the shores of Hell. The only way out is through. To continue the Doom experience, play the shores of Hell and its amazing sequel, Inferno!"

"You've done it! The hideous Cyberdemon lord that ruled the lost Deimos moon base has been slain and you are triumphant! But... where are you? You clamber to the edge of the moon and look down to see the awful truth. Deimos floats above Hell itself! You've never heard of anyone escaping from Hell, but you'll make the bastards sorry they ever heard of you! Quickly, you rappel down to the surface of Hell. Now, it's on to the final chapter of Doom! -- Inferno!"

"The loathsome Spiderdemon that masterminded the invasion of the moon bases and caused so much death has had its ass kicked for all time. A hidden doorway opens and you enter. You've proven too tough for Hell to contain, and now Hell at last plays fair -- for you emerge from the door to see the green fields of Earth! Home at last. You wonder what's been happening on Earth while you were battling evil unleashed. It's good that no hellspawn could have come through that door with you..."

"The Spider Mastermind must have sent forth its legions of hellspawn before your final confrontation with that terrible beast from Hell. But you stepped forward and brought forth eternal damnation and suffering upon the horde as a true hero would in the face of something so evil. Besides, someone was gonna pay for what happened to Daisy, your pet rabbit. But now, you see spread before you more potential pain and gibbitude as a nation of demons run amok in our cities. Next stop, Hell on Earth!"

"You thought an imp was a cute little dude in a red suit with a pitchfork. Where did these brown bastards come from?"

"[Describing the Lost Soul] Dumb. Tough. Flies. On fire. 'Nuff said."

"BFG 9000s are the prize of the military's arsenal. Great for clearing the room of those unwelcome guests. Shoot it and see for yourself."

"You have entered deeply into the infested starport. But something is wrong. The monsters have brought their own reality with them, and the starport's technology is being subverted by their presence. Ahead, you see an outpost of Hell. A fortified zone. If you can get past it, you can penetrate into the haunted heart of the starbase and find the controlling switch which holds Earth's population hostage."

"You have won! Your victory has enabled humankind to evacuate Earth and escape the nightmare. Now you are the only human left on the face of the planet. Cannibal mutations, carnivorous aliens, and evil spirits are your only neighbors. You sit back and wait for death, content that you have saved your species. But then, Earth control beams down a message from space: sensors have located the source of the alien invasion. If you go there, you may be able to block their entry. The alien base is in the heart of your own home city, not far from the starport. Slowly and painfully you get up and return to the fray."

"Congratulations, you've found the secret level! Looks like it's been built by humans, rather than demons. You wonder who the inmates of this corner of Hell will be."

"Congratulations, you've found the super secret level! You'd better blaze through this one!"

"You are at the corrupt heart of the city, surrounded by the corpses of your enemies. You see no way to destroy the creatures entryway on this side, so you clench your teeth and plunge through it. There must be a way to close it on the other side. What do you care if you've got to go through Hell to get to it?"
